Key link is
www.apf.asn.au which is the Australian Parachute Federation which lists pilot minimums.
However I have found that the APF listed minimums don't necessarily match those of your local drop zone and ultimately, as it is the DZs insurance, the DZ requirements win.
In general, they're looking for a set number of hours on the jump plane type (usually 10 in a complex cessna if the DZ flys 206s for example) but in practice I've seen that as long as the CP signs you off then all is fine.
Of course attitude and presentation are key too (not to mention how short of pilots they are)....
