I avoid bogans here, I'm not going on holiday with them.
But I think I am in the last 1000 Australians who hasn't been to any of Vietnam, Croatia and Bali.
as an experienced traveller, one thing I have learnt over time is to avoid Aussie's like the plague. If you're gonna travel, you wanna indulge in the local culture, not hang with people you can hang with at home. There are some exceptions of course (like the FIFA World Cup).
However, if you insist on hanging with Aussie's overseas, there are much better places than Bali. Bali is trash.
