Here in Victoria you can hunt on

Crown land ( if leased with permission)
State Forest
Private Land(with permission)
National Parks (Deer only)

You can hunt all introduced animals but not native animals (only with permit)

You need a game licence for Deer but no bag limit

O/S Visitors can get a temporary licence

Re Loading is legal just need a shooters licence

You can on a Shooters licence own up to 15 firearms any more and you need a alarm system

You can use all types of firearms to hunt except Full Auto,Semi Auto,Pump Shotgun and handgun these are restricted

The above is just the basics but in general I think Victoria has the better firearm/hunting laws......
