What is the difference between the Victorian and Regional Gateway sites?

The Victorian Landcare Gateway includes the Victorian Gateway (this site) and ten Regional Gateway sites.

The Victorian site allows users to search for any information in all eleven sites, while regional sites will generally only show information from that region, but also display news and events from the Victorian site..

Now, if you join as a registered user on the Victorian Gateway, your username will allow access on all regional sites as well, and vice versa.
