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)
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.
