If you have ever sat in a waiting room, stared at a referral letter, or Googled a term your child's therapist just used — this glossary is for you. Australian children's allied-health care comes with its own language: a dense alphabet soup of acronyms, plan names, and clinical labels that can feel overwhelming when you are already anxious about your child's development.
This page collects all 50 of the most common terms in one place, in plain English, written for Australian parents. The sticky letter-index at the top of the page lets you jump straight to any letter. Where a term is explained in more detail in one of our sibling guides — on developmental milestones, when to seek help, the NDIS, or Medicare rebates — we have linked directly there.
Two things worth knowing before you dive in. First, "sensory processing disorder" is not a recognised diagnosis in Australia; you will see "sensory processing difficulties" used here instead. Second, Medicare rebate dollar amounts and MBS item numbers change on 1 July each year, and the HCWA pathway was restructured on 1 March 2026 — where amounts or item numbers matter, we link to the official MBS Online page rather than hardcoding figures that would quickly go out of date.
A
AASW : Australian Association of Social Workers — the professional body representing social workers in Australia. AASW registration is a requirement for social workers who want to bill Medicare under the Better Access initiative. See Medicare rebates.
ACEs : Adverse Childhood Experiences — stressful or traumatic events (such as family violence, parental mental illness, or neglect) that research links to poorer long-term health and developmental outcomes. Knowing a child has significant ACEs can shape how a GP or therapist approaches support. See When to seek help.
ADHD : Attention Deficit Hyperactivity Disorder — a developmental condition affecting concentration, impulse control, and sometimes activity levels, beginning in childhood. ADHD is commonly co-occurring with ASD, DCD, and anxiety. See When to seek help.
AEDC : Australian Early Development Census — a national population measure of children's development and vulnerability collected at school entry (Prep/Kindergarten) every three years. The AEDC surveys five developmental domains and produces data at the local area level, helping communities identify where early support is most needed. See Is my child on track?.
Agency-managed : An NDIS plan managed directly by the National Disability Insurance Agency (NDIA). Agency-managed participants can only access supports from NDIS-registered providers. See NDIS for kids.
AHPRA : Australian Health Practitioner Regulation Agency — the national body that registers and regulates most allied health and medical professionals across Australia, including occupational therapists, speech pathologists, physiotherapists, and psychologists. Checking AHPRA's public register confirms a practitioner is qualified and has no restrictions on their practice. See When to seek help.
Allied health : A broad group of regulated health professions — including speech pathology, occupational therapy, physiotherapy, and psychology — that work alongside doctors to support child development, learning, and wellbeing. Allied health professionals are the core providers in early-intervention services. See When to seek help.
APA : Australian Physiotherapy Association — the national peak body representing and advocating for physiotherapists across Australia. See When to seek help.
APS : Australian Psychological Society — the national peak body for psychologists, supporting evidence-based practice and public understanding of psychology. See Medicare rebates.
ASD : Autism Spectrum Disorder — a lifelong neurodevelopmental condition affecting social communication, behaviour, and sensory processing. ASD presents across a wide range of abilities and support needs. See When to seek help.
B
Better Access : The Better Access to Psychiatrists, Psychologists and General Practitioners through the MBS initiative — a Commonwealth programme that provides Medicare rebates for up to 10 individual mental health sessions per calendar year, accessed via a Mental Health Treatment Plan (MHTP) from a GP or specialist. See Medicare rebates.
Bulk billing : When a health practitioner accepts the Medicare benefit as full payment, so the patient pays nothing out of pocket for that service. Not all allied health providers bulk-bill; whether a provider bulk-bills is separate from whether Medicare covers the service at all. See Medicare rebates.
C
CDM : Chronic Disease Management plan — the former name for the plan now called the GP Chronic Condition Management Plan (GPCCMP). If you see "CDM" in an older referral, it means the same plan. Provides up to 5 Medicare-subsidised allied health sessions per year. See Medicare rebates.
CP : Cerebral Palsy — a developmental disability caused by brain damage (before, during, or shortly after birth) that affects muscle movement, strength, and balance. CP is the most common childhood physical disability in Australia, and children with CP are often eligible for NDIS funding. See NDIS for kids.
D
DCD : Developmental Coordination Disorder — a neurological condition causing persistent difficulties with motor skills such as handwriting, balance, and coordination. DCD is also called dyspraxia. It often occurs alongside ADHD and DLD. See When to seek help.
Developmental delay : When a child's skills in one or more developmental areas — communication, motor, social, or cognitive — are significantly behind those of other children of a similar age. Developmental delay is a descriptive term, not a diagnosis in itself; it prompts further assessment. See Is my child on track?.
Developmental regression : Loss of skills or abilities a child has already achieved — for example, a toilet-trained child who begins wetting again, or a child who stops using words they previously used. Regression always warrants review by a GP or child health nurse. See Is my child on track?.
Developmental surveillance : An ongoing process — not a single test — in which a GP or child health nurse repeatedly checks a child's development, listens to parental concerns, and observes progress over multiple visits. Unlike a formal developmental screen, surveillance happens across ordinary consultations over time. See When to seek help.
DLD : Developmental Language Disorder — when a child has persistent difficulties understanding or using language that affect everyday life, and the difficulties are not explained by another condition such as ASD or hearing loss. DLD is the current preferred term internationally and in Australian clinical practice; the older term was SLI. See Is my child on track?.
E
Early Childhood Partner (EC Partner) : A local organisation funded by the NDIA to deliver the NDIS Early Childhood Approach in a specific region. EC Partners are staffed by early childhood professionals — including occupational therapists and speech pathologists — who help families access supports with or without a formal NDIS plan. See NDIS for kids.
Early intervention : Support provided as early as possible — before or alongside a formal diagnosis — to strengthen a child's development and reduce the long-term impact of developmental delay or disability. The younger the child, the greater the brain's plasticity, which is why early intervention is emphasised in Australian policy. See NDIS for kids.
EC Approach : NDIS Early Childhood Approach — the NDIS pathway for children under 9. Children under 6 with developmental delay (even without a diagnosis) and children under 9 with a confirmed disability can access the EC Approach through a local Early Childhood Partner. See NDIS for kids.
ECEI : Early Childhood Early Intervention — the former name for the NDIS early childhood pathway, expanded and renamed the Early Childhood Approach (EC Approach) in July 2023 when the age limit was raised from 6 to under 9. You may still see ECEI in older plan documents. See NDIS for kids.
Emotional regulation : A child's ability to manage and respond to emotional experiences in ways that are socially appropriate and personally flexible. Emotional regulation is a developmental skill that grows through warm, responsive relationships with parents and carers, and it is commonly targeted in therapy when children show big emotions, meltdowns, or shutdown behaviours. See When to seek help.
Expressive language : The ability to communicate thoughts, feelings, and needs through words, sentences, and gestures — the "output" side of language. A child with strong receptive language may still have delayed expressive language. See Is my child on track?.
F
FASD : Fetal Alcohol Spectrum Disorder — a lifelong condition caused by prenatal alcohol exposure that affects brain development, learning, behaviour, and emotional regulation. FASD is underdiagnosed in Australia and can resemble ADHD or ASD without a thorough developmental history. See When to seek help.
Fine motor skills : Movements using the small muscles of the hands and fingers — such as writing, cutting with scissors, threading beads, and doing up buttons. Fine motor development is assessed as part of routine developmental monitoring and is a core focus for occupational therapists. See Is my child on track?.
FPS : Focussed Psychological Strategies — a set of evidence-based psychological techniques (including cognitive behavioural therapy, psychoeducation, and interpersonal therapy) that can be delivered under a Better Access referral by eligible registered psychologists, occupational therapists, or social workers. See Medicare rebates.
G
Gap fee : The difference between a health practitioner's total charge and the Medicare benefit paid by the government. The gap fee is what you pay out of pocket, and it is not regulated — it varies significantly between providers. Some providers bulk-bill (no gap fee); others charge well above the Medicare schedule fee. See Medicare rebates.
GDD : Global Developmental Delay — when a child is significantly delayed in reaching milestones in two or more developmental areas. GDD is used as a working clinical description for children under 5 while further assessment is underway; it is not a permanent diagnosis. See Is my child on track?.
GP : General Practitioner — a family doctor and usually the first professional parents contact when they have developmental concerns. A GP can write a GPCCMP or MHTP referral plan, refer to a paediatrician or allied health team, and carry out ongoing developmental surveillance. See When to seek help.
GPCCMP : GP Chronic Condition Management Plan — a Medicare plan written by a GP for children (or adults) with a chronic condition, providing up to 5 Medicare-subsidised allied health consultations per calendar year. The GPCCMP replaced the older CDM/EPC item names on 1 July 2025; check MBS Online for current item numbers and rebate amounts. See Medicare rebates.
Gross motor skills : Movements using the large muscles of the arms, legs, and body — such as walking, running, jumping, climbing, and throwing. Gross motor development is tracked as part of milestone assessments and is the main focus of physiotherapy for children. See Is my child on track?.
H
HCWA : Helping Children with Autism — a Medicare-funded pathway that has historically provided up to 20 allied health sessions per year for eligible children with autism. From 1 March 2026, HCWA items were restructured under the Complex Neurodevelopmental Conditions item group. Referral must come from a paediatrician or psychiatrist. Verify current MBS item numbers against MBS Online before using this information to plan services. See Medicare rebates.
Hypersensitive : Oversensitive to sensory input. A hypersensitive child takes in too much sensory information and may react strongly to sounds, textures, lights, or smells that others barely notice. Hypersensitivity is a pattern within sensory processing difficulties (not a standalone diagnosis). See When to seek help.
Hyposensitive : Undersensitive to sensory input. A hyposensitive child takes in too little sensory information and may seek intense movement, appear not to notice pain, or seem unresponsive to sounds at normal volume. Like hypersensitivity, this is a pattern within sensory processing difficulties. See When to seek help.
L
LAC : Local Area Coordinator — an NDIS partner organisation that supports participants aged 9 and over (and adults) to navigate the NDIS, link with community services, and manage their plans. Children under 9 are supported by an Early Childhood Partner rather than an LAC. See NDIS for kids.
M
MBS : Medicare Benefits Schedule — the Australian Government's comprehensive list of medical and allied health services that attract a Medicare rebate, each identified by an item number with a corresponding schedule fee. The MBS is published and updated at MBS Online. See Medicare rebates.
Medicare Safety Net : A government scheme that provides additional Medicare benefits once a family's combined out-of-pocket costs for out-of-hospital Medicare services exceed a set dollar threshold within a calendar year. Once the threshold is crossed, Medicare covers a higher proportion of costs for the rest of that year. See Medicare rebates.
MHCP : Mental Health Care Plan — the colloquial name most people use for the plan that gives access to Better Access psychology sessions. The formal name is the Mental Health Treatment Plan (MHTP). If your GP says "Mental Health Care Plan", they mean an MHTP. See Medicare rebates.
MHTP : Mental Health Treatment Plan — the formal legislative name for the plan written by a GP or eligible specialist that gives patients access to up to 10 Medicare-rebated individual mental health sessions per calendar year through the Better Access initiative. See Medicare rebates.
N
NDIA : National Disability Insurance Agency — the Australian Government agency that administers the NDIS, assesses participant eligibility, approves funding plans, and manages contracts with Early Childhood Partners and Local Area Coordinators. See NDIS for kids.
NDIS : National Disability Insurance Scheme — the Australian Government programme that funds "reasonable and necessary" disability supports for eligible Australians under 65. NDIS funding is based on an individual's support needs, not on household income. See NDIS for kids.
O
OCD : Obsessive-Compulsive Disorder — an anxiety disorder involving unwanted, intrusive thoughts (obsessions) and repetitive behaviours or mental rituals (compulsions) performed to relieve the distress those thoughts cause. OCD can emerge in primary school-aged children and is treated with cognitive behavioural therapy (CBT) and sometimes medication. See When to seek help.
ODD : Oppositional Defiant Disorder — a childhood behaviour disorder characterised by a persistent pattern of angry moods, defiant or argumentative behaviour, and difficulty cooperating with adults, lasting at least six months. ODD commonly co-occurs with ADHD. See When to seek help.
OT : Occupational Therapist — an allied health professional who helps children develop the skills they need for everyday activities: fine motor tasks, sensory processing, self-care, play, and school participation. OTs are among the most commonly accessed early-intervention professionals in Australia. See When to seek help.
OTA : Occupational Therapy Australia — the national peak body representing over 30,000 occupational therapists in Australia, setting professional standards and advocating for the profession. See When to seek help.
P
Paediatrician : A medical specialist in the health and development of children and adolescents. Paediatricians diagnose developmental and medical conditions, order investigations (such as genetic testing or brain imaging), and coordinate specialist care. A paediatrician's report is often required to access NDIS funding or HCWA Medicare items. See When to seek help.
PAMP : Psychiatrist Assessment and Management Plan — a plan prepared by a consultant psychiatrist (rather than a GP) that also allows eligible patients to access Better Access Medicare-rebated allied health sessions. Less commonly encountered than an MHTP but equivalent in function. See Medicare rebates.
PHN : Primary Health Network — one of 31 regional bodies funded by the Australian Government to improve access to primary and mental health care in their local area. PHNs commission services including free or low-cost mental health support that can be an option when Better Access sessions are exhausted. See Medicare rebates.
Physiotherapist : An allied health professional who assesses and treats difficulties with gross motor skills, strength, balance, and physical movement in children. Physiotherapy for children can be funded through NDIS, the GPCCMP, or privately. See When to seek help.
Plan-managed : An NDIS plan managed by a registered plan manager — an organisation that receives and pays invoices from providers on the participant's behalf. Plan management gives families access to both registered and unregistered NDIS providers, and the cost of plan management is funded separately by the NDIS. See NDIS for kids.
Psychologist : An allied health professional trained to assess and treat mental health, behavioural, and learning concerns. Under Better Access, clinical psychologists attract a higher Medicare rebate than general psychologists. Both can deliver Focussed Psychological Strategies (FPS). See Medicare rebates.
R
RACP : Royal Australasian College of Physicians — the body that trains and represents over 30,000 medical specialists across Australia and Aotearoa New Zealand, including paediatricians and child psychiatrists. See When to seek help.
RACGP : Royal Australian College of General Practitioners — the peak body setting standards and advocating for GPs across Australia. The RACGP's "Red Book" (Guidelines for Preventive Activities in General Practice) is the key guide informing developmental checks in primary care. See When to seek help.
Reasonable and necessary : The legal standard the NDIA applies when deciding whether to fund a support through the NDIS. To be funded, a support must relate to the participant's disability, represent value for money, be likely to be effective, and not duplicate mainstream services (such as health or education) that should fund it instead. See NDIS for kids.
Receptive language : The ability to understand spoken language — what a child comprehends when others talk to them. Receptive language typically develops ahead of expressive language; a child may understand far more than they can yet say. See Is my child on track?.
Red flags : Specific developmental signs at particular ages that indicate a child should be assessed promptly — rather than waiting to see whether skills emerge on their own. Red flags are different from typical developmental variation; they signal that review by a GP, child health nurse, or specialist is warranted now. See Is my child on track?.
S
Self-managed : An NDIS plan managed by the participant or their family, who receive NDIS funds directly and pay providers themselves. Self-management offers the most flexibility — families can choose both registered and unregistered providers — but also carries administrative responsibility. See NDIS for kids.
Sensory processing difficulties : A pattern of behaviours in which a child has persistent trouble responding appropriately to everyday sensory information. In Australia, this is a descriptive pattern rather than a formal diagnosis — the term "sensory processing disorder" is not recognised here. A child with sensory processing difficulties may be hypersensitive, hyposensitive, or show a mix of both across different senses. See When to seek help.
SLI : Specific Language Impairment — the older clinical term for what is now called Developmental Language Disorder (DLD). You may see SLI in reports written before around 2017. The underlying description — persistent language difficulties not explained by another condition — is the same. See Is my child on track?.
SPA : Speech Pathology Australia — the national peak body for speech pathologists, representing more than 15,000 members and providing public guidance on communication milestones and evidence-based practice. See When to seek help.
SPD : Sensory Processing Difficulties — the preferred Australian shorthand for challenges in integrating and responding to sensory input. Note that "SPD" is sometimes used internationally to abbreviate "Sensory Processing Disorder", which is not a recognised diagnosis in Australia. When you see "SPD" in an Australian context, it refers to the pattern of difficulties, not a disorder. See When to seek help.
Speech pathologist : An allied health professional who assesses and treats difficulties with speech sounds, language comprehension and expression, voice, fluency (including stuttering), and swallowing. No referral is needed to book a private speech pathology appointment, but a GP referral is required to access Medicare rebates for the service. See When to seek help.
