Thank you everyone. Your thoughts are helpful.
I am lucky enough to have dual nationality, so that aspect of working is easier for me. I also have both an undergraduate and post graduate degree , & am registered with all appropriate UK organizations / boards.
My aesthetic practice here in UK is strictly governed and totally above board. All procedures are regulated by the NMC / CQC etc. I'd hope to work as ethically and carefully in Australia.
Just as you've mentioned happening in Oz, we do have unqualified charletons here, who offer treatments using illegally sourced medication / products from China or somesuch country. Ironically, because they are not medically registered, they can get away with it, and damage a lot of people to boot! It is a ridiculous situation.
