I reckon we'll be getting "beamed" around by Canadians pretending to be Scottish before the drone menace becomes mass transportation.
In any case UBER usurped a certain bunch of rich individuals who were holding the taxi system to ransom, so the government sort of 'let' it happen. Now nobody can make any decent money out of land transportation, so the government is happy, and they have no responsibility, because UBER made sure that's all down to each driver. UBER worked because there was no full legal definition for what they did, they are not a taxi company, or a bus company, or even a specialty hire vehicle. Aviation does not have loopholes in that regard as the CASA law clearly defines commercial vs private operations and limits cost sharing operations to non profit.
If you want internationals to have open slather in Australia, then ask them for open rights to their country. I think I already know the response to that...
