Ask An Australian

I'm applying for a working holiday visa and I'm planning on arriving the first week of September but I don't have a drivers license and, obviously, I cannot get one in Australia without citizenship - how hard would it be for me to get/work a job without a car? Given that I would most likely start with farm jobs, would it be possible to do so without having a license?

I'm asking because it would take approximately three or four more months for me to get one where I live
