Places I have been

So Australian's generally have a reputation for being travellers and therefore well travelled, and going through the list of countries I have visited (not counting transiting countries, that's just cheating), I'm not too sure that I belong in the same group. Never less, here is the list of countries that I have visited in my 30 odd years of existence:

1. Australia
2. Bosnia Herzegovina
3. Cambodia
4. Canada
5. (Mainland) China
6. Cook Islands
7. Croatia
8. England
9. Hong Kong
10. Hungary
11. Macau
12. Montenegro
13. New Zealand
14. Serbia
15. Singapore
16. Tahiti
17. Thailand
18. United States
19. Vietnam

With plans this year to visit between 4-5 new countries, I can safely say that I'm at least on my way to be world traveller. How many countries have you visited?
