Centrelink income + your measly rideshare earnings "to the limit" are all taxable income Sherlock.Those drivers need to re-evaluate how they do things. I make a good profit every week. Less so now obviously but still doing ok.
Even after Centrelink comes in, I'll be working to the limit of what I can earn without affecting my payment.
Taxes don't come into it. Obviously they have to be paid but if someone isn't making a profit, they don't have to pay the taxes....
