I am struggling to find a firm answer to my question. Here's my situation:
I am looking to travel to Australia in December for a few weeks to visit my brother, who moved there a few years ago. I am a British national, but 10 years ago (when I was 18) I made a mistake and landed myself a criminal conviction for a very minor cannabis possession charge, which resulted in a £600 fine. I haven't been in trouble since and it is a huge embarrassment.
Obviously this meets the ETA visa requirement of not having a conviction that resulted in a sentence of more than 12 months. But I don't want to accidentally fall foul of the rules and be seen to have misrepresented myself.
Any guidance would be appreciated.
