If you're in Western Australia, and interested in Theravada, the best teacher for you would be Ajahn Brahm. You can find videos of his talks on the Youtube channel of the Buddhist Society of Western Australia (BSWA) and also here. I don't reside in Australia, but I've attended Ajahn Brahm's talks when he visited my city. The next most senior monks at BSWA after Ajahn Brahm seem to be Ajahn Appichato and Ajahn Brahmali who may also be helpful.
Although I am not familiar with him, if you stay in Victoria, Ajahn Kalyano of the Buddha Bodhivana Monastery can be your teacher. Here's a Youtube video of one of his talks.
In New South Wales, there's the Bodhisaddha Forest Monastery (although I do not know who are the teachers there) and Wat Buddha Dhamma (whose abbot seems to be Ajahn Khemavaro). Perhaps, Ajahn Khemavaro can be your teacher. Here's a Youtube video of his talk. Here's another talk from him.
The teachers and monasteries above are all from the Thai Forest Tradition, of the lineage of Ajahn Chah. There may be other monasteries from this tradition in other parts of Australia.

Patrick Kearney is a Mahasi teacher in NSW Australia.
"Patrick Kearney is the best mindfulness teacher it has been my experience to work with. I appreciate the depth of his insights into the Buddhaβs teaching, meanings that have resonated with me personally. Few teachers can help smooth a studentβs own experience with mindfulness practice as he does. Last, and hardly least, Patrick has a huge heart, and this manifests in all his teachings. I cannot recommend a workshop with Patrick Kearney highly enough."
