Thanks Mick, great work mate!!
It's a 6x4 tourer made by either Pierce engineering or Coerts in Noosa. It looks like the old model, which is discernable by the roof shape, the newer models had a 100mm height added above the windscreen. They were famous along with the arkana and preferred until the advent of the Mits Canter, which were more capable and carry more weight.
The construction was monocoque, spot welded and a guaranteed 5 kg of bog with every bus!!! They also had issues with major cracking of the join above the windscreen. This was over come with various methods, like using Oz Easts fibreglass windscreen surrounds and only Sikaflex where the join was originally below the screen. Successful, but you had to change the door locks every machinery inspection.
I'm still keen depending on the price......
