On the day you claim Youth Allowance you must be an Australian resident, and in Australia.
You must continue to meet the residence rules for as long as you get this payment.
If you’re a non-protected Special Category visa holder, and have lived in Australia for at least 10 years without a break since 27 February 2001, you may be able to get Youth Allowance for up to 6 months. This can only happen once.
If you qualify this way, the newly arrived residents waiting period won’t apply.
