Anyone got any good places online to find farmwork? Currently in adelaide but would be willing to relocate given a decent enough paid job?

You need to change your location.Also have you checked gumtree.Not sure of your situation but have you considered cleaning jobs.That pays around $25 per hour privately.Good luck.

If you want seasonal work , Kununarra was very good but dont expect to make a lot as its very expensive.

If the only reason you're wanting farm work is to fulfil the 3 months rural requirement for a second WHV, are you aware that all of SA is accepted as rural for this purpose, including Adelaide?

Agree with irishbloo re cleaning, it's not bad 'holiday' money and there always seems to be private work available.

Ah thanks ppl i'll have a ganders at cleaning :-)

Indeed - list of regional areas, and list of specified work.
