Call Adelaide TCU (number in ersa) to discuss on the day you’re interested in doing it.
Clearances for the Hope Valley VFR route and / or orbits are difficult to facilitate during the week due to Adelaide traffic, but may be available on the weekend if you’re happy to wait for it.
Low level coastal from PNL - OHB (and vice-versa) is much easier to facilitate even during the week, with delays.
