maybe the ADR's only specify spring loading not height, so states can vary what height they allow. I'm only guessing here - doesn't make sense as you say.

Nigel,a good friend of mine is a transport inspector and I asked him the other day about suspension lifts (2") and he said that all suspension lifts are illegal unless you get written permission from QLD transport and have documentation from the spring/coil manufacturer stating that the product was made/engineered to fit that particular vehicle. He even sought advise from his supervisor on this issue and the supervisor said the same thing.
Further evidence that this is the correct thing to do, I have just been to my 4wd club meeting tonight and a few of the members with the high lift suspension said that they had to do this. Not only for road worthiness reasons but to keep the insurance companies happy also.

Oh, by the way, I did query him about that booklet and he said that the booklet does give all the requirements you need specifically for suspension lifts. My advice to you is to do what I did and get it straight from the houses' mouth (QLD Transport).

A modification, in terms of road worthyness, is anything departing from factory specs. Simple. If you put on bigger tyres than that stated on the tyre placard, it is deemed a modification from standard. ADR's have little to do with state registration rules, the two are seperate and variable.

From what I understand from when I got mine engineered, 2inch is about the max, as you will notice thats the max that most insurance companies will allow too.

As for body lift, any body lift needs engineering.

Tires, I think its 15% above std, but not sure. Vicroads site has that one on there.
