Glad you are joining us. Hard for me to recommend a saw, not knowing what is available, but like has been said, we have some Australian members that can help out. It is worth getting as best you can afford, make the hobby more enjoyable, but a lot can be done with cheap, if you have patience.
Check out my hat in my avatar picture. "Driza-bone" hat my son bought for me on one of his visits to Australia. I love it. I'd love to visit Australia.
