Linon
Yes, you've found it!
Here's the caption that was with the photo:
This well-dressed Ipswich couple are driving an early Linon voiturette (light car), probably a 1902 model with a single cylinder, 3 1/2 horsepower De Dion-Bouton engine. The man is dressed in long pants, jacket and cap, and the woman is wearing a large, feathered hat secured with a scarf.
Linon cars were built in Belgium by a father & son company of former bicycle makers. The car in the photograph is unusual in that the drive is taken from the front mounted engine to the rear wheels by a flat twisted belt, a system more commonly used to drive agricultural machinery at the time. Secured to the front of the dashboard, behind the oil lamps, is a glass and metal lubricator device.
So the picture was not from Europe
I had made a note that the picture was from Ipswich, but didn't know about the Australia part!
