Stunty, try Mick at SAE ( Hardy's maintenance hangar, next to Hardy's). He's got a strutted model 210 ( J or K ?), 4+2 seating that he used to private hire.
franksnbeans, January is a bit of a problem heading north out of Vic, inland (Alice, Birdsville, Longreach etc ) are all stinking hot places to be at that time of the year, and the coastal areas of Oz north of 20 Sth Latitude are subject to "The Wet". Provided you have time to spare, no "pressonitis", you can get around with care, depending on your interests, the Gulf country, esp Burketown, is spectacular at that time of the year, BUT you will need, as already advised, to do your flying between 9:00am and 2:00pm, before the storms develop. Expect daily disruptions to flying, do not attempt IFR in the remote areas except as a last resort, because the ceiling will be around 500' and the MDA's around 650'. There will be radio towers around 300' near most outback towns, and around every 50kms, esp near roads between towns. Be careful, don't scudrun in unfamiliar territory, keep a back door plan open, accept that you can expect to be weathered in, and you will see spectacular scenery. Better still, avoid the risk and go to Lord Howe, but practice xwind techniques 1st, and get fit, coz there's lots of great walking and climbing to experience. Or go to Tassie via the islands.
