What's the oldest active government Twitter account in Australia?

I've done a review of the registration dates for Twitter accounts from agencies at all levels of government in Australia and identified what I believe to be the oldest account.

Established in November 2007, the oldest government Twitter account in Australia is from Narromine, a small local council in Central West NSW.

You'll find them still tweeting regularly at @Narromine

The second oldest was @rfsmajorfires, providing automated updates about major fire risks in NSW since December 2007 and the third was @questacon in May 2008, providing educational and exhibition news.

The full timeline is available as a tab in my Australian governments Twitter accounts spreadsheet.

Chart of the timeline for government agency Twitter registrations by month and a cumulative registration rate is below.

It excludes three suspended accounts (for which I cannot determine registration date).
