A free autism assessment in Australia is possible through public services, which are offered at no cost to families but often have long waiting lists. Private assessments can be expensive, and what you pay depends on the clinician and whether Medicare rebates apply (Raising Children Network).
This guide sets out what is known about cost, who may get help with fees and how to compare your options. If you are starting from scratch, read how to get an autism diagnosis in Australia first.
Cost depends on whether you use a public or private service and on your age.
The schedule fee is the Medicare benchmark, not what every clinician charges, so ask for the full fee in writing (MBS Online, item 135).

It depends on the service. Public assessments are offered at no cost to families but often have long waiting lists, while private assessments can be expensive. Ask each clinician for a written quote and check which Medicare rebates apply to you.
