Needed: Web cams links in Canada and Australia

Hello, I am a Teacher of English and I use live webcams during the lessons to show the places we study to the pupils.

I've got a number of good links in Britain and in the USA, but in a few weeks we begin studying Canada, Australia and New Zealand. Does anyone (especially the ones who live in those countries) have any good links that could show really good views of these countries in order that my pupils could have a good idea of the countries?

(I'll also appreciate any good links in any of the English or Spanish speaking countries)

Thanks in advance. Dew 2007
