I am loving the Australian Civilization is finally an 'official' playable faction in Civilization VI. No longer do I need to send my non-Australian civilization to the Australian mainland, found cities there and attack city states/civilizations who had previously lived there. Nor do I have to rename my leader and civilization to Bobby Hawk and Aussie respectively.
John Curtin makes an interesting choice as leader and I'm finding their unique military unit (digger - industrial era unit - replaces infantry) and unique improvement (outback station - allows them to get some food from desert tiles) to be useful, as is their leader's benefit (cities on the coast receive benefits).
Their starting location means that if you want to make contact with other civilizations early on, you'll need to build galleys and send them out early on. Asia/Africa/Europe are quite easy to get to, if the trip takes a long time to get there. Reaching the Americas, however, seems to require one to wait for their ships to be able to enter deep waters. Also, to get to New Zealand, I found it necessary to go through the South East Asian/South Pacific island nations.
Outback Station comes during the medieval age, and digger comes during the industrial age. So, you need to be patient to get the unique items for the Australian Civilization, but I don't mind the wait.
Yes, I rather enjoy the Australian faction in Civilization VI, but that could well be to do with the fact that I'm Australian. I am currently at 1040 AD in game (as the game tells the time) and the only foreign unit to come to the Australian mainland was a Japanese missionary who spread Buddhism to one of my cities.
There were a few barbarian outposts and friendly villages at the start of the game, but I haven't had any barbarians around for a long time now.
