In victoria, the maximum allowable ttrack increase is 25mm on the front and 50mm on the rear (if you've dont have independant suspension). This is stated in "Vehicle Standards Information 8"
http://www.vicroads.vic.gov.au/NR/rdonl ... 0/VSI8.pdf
Is the 25mm increase refering to the stock standard track or the width of the track when you have the maximum width of tyre that is specified on the tyre placard (i.e. 10" wide tyres on a patrol mq)??
I want my car to be completely road worthy so i don't get scammed by the insurance company.

When the engineer measured the track on the Hummer replica it was from the centre of the tyres.
It would not matter if the truck has skinny or fat tyres, If you have the correct offset Patrol rim the centre of the tyre will always be the same, would'nt it ??

Can anyone confirm that the track width is measured from the centres of the tyres?

Correct. Centre of tyre to centre of the other tyre on the same axle whilst the vehicle is on level ground.
Off set rims can alter the track. Wheel spacers will increase the track.

I Also found proof of this on the vic roads website in the "roadworthy requirements" PDF file.
