Farm Work - NOT FOR 88 DAYS

My friend and I are currently in Melbourne - we are British so DO NOT need to complete 88 days for our visa, however we would like to work on a farm in order to save money as hospitality here is hard to find full time work. I read about some farms don’t qualify for 88 days but is finding ones that don’t. Facebook doesn’t seem to be any help either just inundated with false advertisements and people wanting to extend their visa. Any help or advice appreciated!
