On uni park max dumbell is 50K with a big range from there down. BUT I stress the uni gym is ****! Far too small and not enough equiptment to get want you want. I am deffinatly going with a different gym next year.
Though if you get in to the first team of an AU team you get use (with bronze sports membership) of the strngth and conditioning room. Which (from what I have seen from it) looks really nice and no one ever uses it.
