Until we sort out transport issues in Australia, tourism will languish on the sidelines in a manner somewhat analogous to Hans Christian Andersen's Little Mermaid as she loses her voice.
Notwithstanding the tendency for politicians to obfuscate about the necessary 'strategic plan,' the essential link between the 2 Ts [Tourism & Transport] is broken, and will remain so until 'Australian political will' provides for its repair.
Unquestionably, transport is both "key" to the problem and the solution.
...& unquestionably Tokyo has 'transport' worked out!
