The NDIS uses the phrase 'short term accommodation' as an alternative to respite.
Having short term accomodation ('respite') included in your plan is often dependant on what goals you go into your planning meeting with and what is accepted by the NDIS.
Goals that provide funding for short term accomodation can include:
Time for my family to have a break and recharge
Learn to live independently
Transitioning into supported accomodation
Remember goals are always framed from the participant's perspective not the family's.
