Can we get married in Australia if we are not citizens?

Hi there, I am wondering if you can help me. Myself and my partner are currently residing in Canberra but we are not Australian citizens, we are English citizens, we are here on two year working visas. We are due to get married back in England in December but in order to make it 'legal' we have been advised that we have to get married officially here first. As we will be here on our own we only want something very small and personal, basically it's just to allow us to get married in the uk. Sorry if I have confused you as I appreciate it's a bit complicated but if you could let me know your thoughts it would be much appreciated xx
