Toy, that is a good point. My feeling on it as an ignorant local who has never done it. Is if he car has current registration from any State; than a Road Worthy Inspection to change the registration over to the State you wish to sell in isn't that difficult, just a process really and perhaps 1/2 to 1 day mucking around. No matter which State you sell in, the vehicle has to meet a standard, so if any repairs have to be done like a new windscreen, or various oil leaks, perhaps brakes etc, may be more of a head ache in time and money.

I'll drop in my local transport department next week and see what I can find. Toy is correct, each state has it's spin on it, New South Whales (NSW) and Victoria (Vic) would be the more stringent ones. Hopefully my Queensland (Qld) department has a good overview.
Have you any thoughts on where you plan to enter and exit. Arriving East, leaving West makes sense, or vice versa. Generally it's 12 500 mile to do the lap but that's only the outside. Add another 1900mile to bisect the country Nth to Sth through the centre.
Plenty of good stuff in the interior but your options on how it's done can be limited. If you are up to it, an "prepared" there are some nice remote back country roads to make it easier from a latitudinal perspective, but if it goes pear shaped you just might not see anyone for a week or so. All part of the fun and frustration of panning a trip to a big country.
Unfortunately central Aus and Western Australia (WA) are a long way no matter where you are, but fortunately also have some of the best the country has to offer. If you like arid, less populated, big skies, loads of serenity, less frills or BS than these states certainly have it. Across the top from Darwin in the Northern Territory (NT) to the Kimberley's in Nth Wst WA is a huge amount of raw Australia. It's becoming popular with grey nomads, and den be very humid but that's life. Brooms a tourist trap, but Sth of there in spring is a mass of wild flowers. There are some nice beach camping spots with reefs just off the shore (25m) to take in plenty of marine life as well. PM me for those.
In the centre, West and Est Macdonald Ranges, Kings Canyon,and Uluru around Alice Spring (NT) would have to be some of the most interesting and amazing land formations in the country. And due Sth from Alice on the way to Adelaide the Flinders Rangers and Gammon Rangers are just beautiful. Not surprising artists flock to the area to capture it's colours. Oh I feel like a holiday now myself.
Back on task, camper trailers. Cub and Campomatic are a couple of the original and worthy of inspection. Kimberley is a well known, respected, but an expansive brad. They do hire I believe, have second hand ones, or have some buy back option I think.. My mate dropped 55K on one, dragged it around the country for 12 months with his family. Had diesel hot water, big fridge, heaps of water, dunny, all the bells and whistles, easy, fast, water proof, it just worked. When he got home he was pondering if he should sell it, though he could get 40-45 for it. For 12 months easy and fast camping accommodation with the family for 10 to 15K isn't bad money spent in my book. Maybe something that could work for you. I'd imagine the band would move easily at the end as well. Only down side that I see besides the price is, is that they are a 1.5T camper trailer.
Japanese 4cyl models to look for. I do admit these may struggle a bit towing a 1.5 trailer. Perhaps it depends if you want to race around a country or see it.
Mitsubishi Trition. 04,05 3.2 diesel was a good one.
Mazda Bravo- Ford Courier 04-06 2.5Td
Of course any of there cars from 06 to now all improve in power, but also plastic and electronics. Wikipedia is a good overview.
Anyway till next time.
