Local area comps are usually lucky to have 2-3 refs with more than the most basic ref training. Amateur comps = amateur refs.
I've played in three local area comps in Sydney and the standard of reffing is pretty low across all three, but since they are doing it for very little money you cannot complain, at least they turn up week in and week out (unlike soccer/league refs!)
Worst comp I have ever been in was a trial summer comp (8 weeks and finals) at Castle Hill where each team had to provide a ref to the game before or after your own, some teams made really dodgy to ensure that other teams didnt make the finals. My team ended up losing the final (thankfully reffed by proper officials) but it was the worst comp I played in for all the cheating and carrying on that occurred.
