I'm so grateful to be eligible for benefits when I can't work. This week I can't work because my son has fallen sick and my mother in law who looks after him has fallen sick too. I had to cancel 2 shifts at work (am casual) and my husband is a student. So my next payment will be all from benefits and I won't be able to work next week cause I'll be having surgery. So as long as you qualify for it and are eligibile to receive it why not? You need some kind of wage to get by. I'm sure everyone would love to have a high paying wage to support their family but don't feel bad about having to rely on centrelink payments. It's not that easy to just find a job especially with a young family. So do what you need to do. Go down to Melbourne or wherever and see what happens. Hopefully cold calling might do the trick.
Good luck with everything.
