Being down here in the land of big lizards, and six foot rodents.... Sydney has good saltwater fishing, and a three hour drive inland gets you to some good trout water. We also have the murray cod, and the Australian bass. All good on lures and fly. There is a lot of info about fishing ESPECIALLY salt water, but the fresh can be very good. The type of gear he has is going to define what he wants to target. Let me know if you want any more info.
With regard what he can take you, not much i am afraid. We get the same sort of stuff you do, but I can get you a couple of online stores local to oz, and you can have a look see.. just let me know.
Cheers for now,
Bradders
