I'm in...
9 Day BKK/SYD will do me fine, and I just checked my CRC (from when I was cabin crew) and it's only at Basic Disclosure level.
You only need an enhanced check if you are in sole charge of children or vulnerable adults.
The big question is when my ballot paper arrives again (I only left crew two years ago), do I vote yes so I can spend a week flying around? Perhaps I should ask for advice on the BASSA forum as I still have access to that?
