I'd be interested to hear what you consider Asia to be. The reason is that I was looking for some Australian news on the bbc news site. It used to be under a category called "Asia-Pacific" but now is called just "Asia".
This is the front page for world news
http://www.bbc.co.uk/news/world/ and it lists Africa, Europe, Middle East etc and Asia. Included in Asia are Australia and New Zealand.
I suppose Australia and New Zealand are correctly listed as part of Asia but I don't consider them to be Asian countries in the normal sense of things.
So, what do you think? If you were looking for news about Australia or New Zealand would you automatically think "Asia"?
