Hi dazza,
Firstly, welcome from another Queenslander.
Re the dash drawing, note that Grumblebuns link is for a Federal S2 (Type 65) which is a little different from the UK cars we mostly got here in Oz.
While flipping the drawing would likely work (?), there's a few holes for things we didn't get, too - hazard lights and brake fail, for instance.
Below is a pic of what I'd expect a Type 54 to look like.
