Welcome Michael!
Head for Wallan - brilliant idea!
I have observed from Romsey and East/North/West are quite reasonable skies. To the south will be ginormous Melbourne skyglow, but you can still observe that direction - not impossible.
Obviously try to get away from local lights as much as you can and let your eyes dark adapt well.
Lots of targets. Earlier in the evening, after you've had a good look at Jupiter, turn to Scorpius and Sagittarius. The swing to the north and see if you can catch the globular M13 in Hercules before it sets too far. Then look at the lovely double star Alberio in Cygnus, and try to pick up the planetary nebula, the Ring Nebula (M57) in Lyra. Then tour your northern sky later in the night - globular M15 in Pegasus, galaxy M31 (even though it's low to the horizon) in Andromeda, galaxy M33 in Triangulum to name a few easy targets. Also the Pleiades star cluster (M45) in Taurus, then the Orion Nebula (M42) on the Sword of Orion.
You'll have a great time.
