How to buy Dero Australia?

I'm interested in purchasing Dero, but I'm unsure of the process in Australia. Could you walk me through the steps of how to buy Dero in this country? I'd like to know the best exchanges to use, what forms of payment are accepted, and if there are any regulations or taxes I should be aware of. Additionally, I'm curious about the security measures I should take to protect my investment. Can you provide some guidance on that as well?
