Thinking of planning a trip to Australia for some gambling as well as sight seeing. Any tips from the pros?

Where is the best place i can exchange some USD to AUD? looking to probably exchange 10-20k if i start losing.

Do the casinos exchange USD to AUD?

Im looking to hit the east coast of Australia, doing like a Brisbane down to Victoria kind of trip.

Any recommendations on travel? places to stay, transportation, etc. anything at all that would be helpful information.

Do the casinos simply back off like in the US? Are they more like social clubs like Ireland where in their terms of signing up it states no APing? Is it safe to AP?

Are their BJ rules any majorly different than the US? like ENHC, early surrender, or anything?

Please, any and all info is greatly appreciated.
