To be considered reasonable and necessary, a support must be:

  • related to your child’s disability
  • value for money
  • likely to work and
  • benefit your child
  • based on evidence.


Reasonable and necessary supports don’t include day-to-day living costs that aren’t related to your child’s disability support needs.

Reasonable and necessary supports take into account any informal supports that your child already has. Informal supports might include things like help and support your child and family get from:

  • friends and extended family
  • local and community services
  • the health and education systems.


In general, reasonable and necessary supports should help children to:

  • become more independent
  • take part in social and community activities
  • look after their health and wellbeing.
