Onyx - thank you. that's true, I can always just settle in Aus if it's not working out.

double trouble - thanks, there's some very good advice in your post. I think its fantastic your kids can speak three languages, so many benefits for them. As for the family, I have only just met them and they don't seem like they would try to make us stay, but really how could I know, I don't know them very well. Me being there would have no effect on my little ones fathers relationships, but I have wondered how it would effect mine, and if being a single mum would rule me out completely for most men there. I'd say it would be hard for me. Great idea about putting flight money aside too, I'll remember that. The country with the best options for children is definitely Australia for me too, but I am just so drawn to Tanzania that I feel I need to give it a go.

wysiwyg - That's true, he is only young so I'm thinking I might be ok with short trips now, but when he is at school age maybe we'll spend the year in Aus and go to Tanzania for the 6 week year end school holidays maybe. A year travelling Europe sounds awesome, what a fantastic experience!
