Are Tesla's Autopilot features legal on Australian roads?

Throwing a Tesla Model S, complete with the latest 7.0 software, into Auto Park is thrilling precisely because of the way it seems to toe the line of autonomous driving

When a car has the ability to change lanes for you, the temptation to go hands-free is strong, even if the car company advises you not to. With Australian states yet to comprehensively legislate and allow fully-automated cars on the road beyond preliminary trials, Tesla's latest Autopilot features, including Auto Lane Change, Auto Park and Autosteer, feel as if they stray close to the legal line.
