Yes it can get a bit expensive, especially if you don't do it with regulars who have an arrangement.
There are a few guys I can put you in touch with (probably over Facebook) but what is on depends on when your down, there are regular big games as well as a few smaller "club days".
If your ok with speed ball you will get to see RC's wimpy and his glorious CCM that he won't let me touch in a tournament held in Victoria called PAVS.
In short send me a msg on here or check out Bushball.net for players by players.
(Australian bushball site) when your down and ill help you out.
