Dear New Member~
As far as I know a single parent benefit finishes when the youngest child turns 14, and if you are unemployed and provided there are no other circumstances Jobseeker begins, however you had best check this with fully Centerlink setting out your circumstances..
Food vouchers are sometimes issued by benevolent societies such as St Vincent De Paul and Anglicare, so I'd suggest you contact them too. Anglicare is particularly good with financial advice.
