Yes, unquestionably C. hederifolium. At first I thought "what is it doing flowering at this time of year?" but then I remembered the reversal of seasons between the two hemispheres!
It's the most common, easiest, and perhaps most rewarding of cyclamen species. Seed will ripen in early summer (December, ozzie time) and if collected then and sown, you can soon have your garden full of it. Or you can leave the seed to the ants to carry around and plant in unexpectedly artistic sites.
