I just found out that hook turns exist in Tasmania! Although only for bicycles. To quote the Tasmanian Road Rules 2019:
**35.** **Optional hook turn by a bicycle rider**
(1) The rider of a bicycle turning right at an intersection without a *hook turn only sign*, or a *no hook turn by bicycles sign*, may turn right at the intersection by making … a hook turn under this rule.
(it goes on a bit after that)
