hi BJ
firstly let me tell u that u need to do a lot of homework otherwise a group tour is the way to go.
u need a Western Australian Miner Right--$25aud
u will not be able to bring a li-ion battery on the plane
its hot in WA from now through to April next year temps will be regularly in the high 30'c-40'sC over 100'F
plan your trip as well as u can coz most of the time u will b driving past gold looking for gold.
u will need a vehicle preferably a 4X4 Toyota or similar. u can hire campers to tour with and they have a bed, water, fridge, power etc etc.
how long r u coming for?
i'm 1000 miles north of Perth and distance isn't a problem for me.
just something to get u started.
regards
oneday
