Can't address the width fitment, but man, that is one short sidewall.
If you're more than 35 years old, I'd worry about kidney damage unless you're driving on the smoothest of roads. You'll probably feel the impact from crossing the painted stripes on the road.
- Just a personal opinion from someone more than 35 years old and surrounded by roads with lots of cracks, frost heaves, patches, and potholes. I'm about ready to go to a 245/75R14 just for a smooth ride! ;-)
(Yes, I realize Australia probably doesn't have frost and ice issues, but I don't know your road quality. I believe paving standards have declined since the popularity of light trucks and SUVs.)
You can find good fitment info at www.tirerack.com
and probably other sites. In brief, tire width (235 mm or 9.25 inches) will probably be better on a 9 - 9.5 inch rim.
In the USA, 19inch wheels and tires seem to have limited options and high prices.
