Australian treats physical gold in the same category as Australian Notes in regards to Airport security. You have to declare any monetary value of $10,000 or more in "Money" which includes physical notes or gold and silver. They recommend holding Gold bullion on your persons in your hand luggage for safe keeping.

So it's recommended to carry your 572 Australian notes or 2cm thick gold bar in your hand luggage, however both of these items require declaration before take off.

The local coffee shop requires both Australian Notes and Gold to be converted into the local currency, Which both Gold and Australian notes are capable of doing.

So to summarise.


The gold is lighter
The gold is smaller
Gold shares the problem of Australian dollars in requiring declaration to the airport authorities before take off.
Gold shares the problem of being transferred into a local currency.
