Looks a lot like my old Minolta SRT-101 with some added on electronics. It can do Aperture Priority metering (so you just set the Aperture on the lens and the camera will select the shutter speed to give the correct exposure). You can also set the shutter speed manually.
The lens is basic, similar to a kit lens on todays cameras. There are plenty of very nice manual focus Minolta lenses out there, I always had a couple Rokkor-X lenses and it would help to have at least one fast prime lens as you will probably be using film in the ISO 100 to 400 range. The 50mm f/1.7 Rokkor-X is probably the cheapest (I think the -X designation was used in the U.S.). As the camera does not have automatic control of aperture it can probably use older Minolta lenses with no problem.
Price seems a bit on the high side. I would think 200 Australian is a decent price. If it was the higher up X570 (or X500 depending on market) the price would be about right.
However, if the camera is in very good condition then it is certainly a decent camera to use for learning photography or just having fun with film. It has a very good meter (typical of many Minolta cameras) and nice viewfinder equal to the their higher end models so it should be easy to focus. It will hold up to a lot of abuse for a plastic body camera. It can take a cable release (get one if you don't have one), but does not have a PC socket for external flash (have to use the hotshoe).
