Can a UK visitor use an Australian betting app while on holiday?

How to use this answer

A definitive win, loss, void or refund cannot be established from the question alone. Identify the operator, the exact market, the date and the relevant official result, then check the rules that applied to the bet.

Check the applicable law where the user is physically located and where the operator is licensed. A gambling site that operates lawfully in one country is not automatically permitted to accept or advertise to another.
