As Chris said, the Melbourne/Brisbane border does a circle around Sydney. It does an arc from near BOYSY, to DIPSO then around to just past OPTIC.

There's no real concern about the lack of radar coverage. Outside of that, ATC use different methods of determining your position, for example ADS-B or position reports. Using those, they then separate you out using an alternate set of standards.
