Just come across WanderWomen Write contest. Although it's run by a Seattle based organisation, it is open to writers around the world. I've been in touch by email and double checked that point.
The prize is a 10 day trip to Cambodia and Vietnam but you have to pay to get out there from where ever you live so that's why they can make it international.
The contest is open to women, whether they are newly-emerging or seasoned travel writers. and last year they had more than 300 entries.
DEADLINE: December 31 2010 and the winning writers will be announced in mid-February.
