Imagine being so totally alone (except for the dude following you in a car so you don't cheat) like that. Just you, your bike, and the beautiful country all around you (and a dude following you in a car to make sure you don't cheat)
...I mean, I couldn't say it off the top of my head, but it does have a name!
(it's the Cape York Peninsula, apparently. Apparently the population there is still 60% Indigenous, and they've successfully won native title rights to 45% of the land. The peninsula is largely coterminous with the traditional extent of the Paman languages, one of the two main branches of Pama-Nyungan, the largest language family in Australia — and among the Paman languages is Guugu Yimithirr, the language the word "kangaroo" is from. The Cape York Peninsula is also home to a number of Indigenous sign languages, and there is even a dialect of Auslan heavily borrowing from these, spoken by Deaf Indigenous people on the peninsula. Way cool!)
The Australian wildlife thing is pretty exaggerated. If you stick to the roads you'd probably only rarely get close to a wild animal, and it'll just be vibing along and leave you be.
Except in far north Queensland and parts of the NT which were avoided for a reason.
