Hun get him to contact ASPECT or Autism Australia. They are in NSW and have a parent helpline with heaps of information. I have found them to be helpful, you do have to phone and leave a msg and then they phone you back. But they have a lot of information as to help at their finger tips.

A few things:

1) for sensory issues go to an OT. With a diagnosis they are entitled to financial help for OT appts etc

2) if TT is an issue, and the child is over 5, talk to Blue Care re: incontinence help. They have heaps of help as far as free pull ups, dry nights etc.

Thats all I can think of ATM, there's heaps of info out there. You just have to look for it yourself, ykwim?
