I found out a month ago, the school I am doing the Japanese lessons through has notified the government. And the past few payments I have been getting educational allowance on top of the dole. Which is only $8 per fortnight.
A few months back I looked at how much you can earn to supplement the dole. I think from memory its only $250 a week, or $50 per day. Any more than that and you would have to tell centerlink so they can adjust your dole payments.
