Who is using open source software in New Zealand or Australia?

The article over here talks about differences between European and U.S. adoption of open source. While the article focuses mostly on how those differences impact open source licensing, it also makes the following points:

Throughout Europe governments lead the adoption of open-source software. ... In my experience, government IT workers (especially in Europe) tend to buy into the ideals of open source more fully than their private-sector counterparts. ...

This is somewhat less true of North America, where most open-source adoption is driven by enterprises seeking to lower costs and maximize innovation. In my experience, their developers buy into the ideals of open source but their legal departments generally do not...

This makes me wonder what the situation is like in this part of the world, New Zealand or Australia? What are the main drivers for the adoption of open source here? Who is adopting open source?

As I said before, I get the impression that open source adoption generally is lacking a bit in New Zealand (don't have first hand experience in Australia with this, so if someone has an opinion about that, please let me know). But the recent open source discussion paper from the Ministry of Justice certainly was very encouraging in that respect.

So, if you have any experiences with commercial or government organisations in New Zealand or Australia, which thought about adopting open source or actually have done it at least to some extent, I would love to know about it. What are their reasons for or against it? Is the government or the enterprise more active in that respect?

Any feedback is greatly appreciated.
