About 1.5m tweets have now been sent by Australian councils and government agencies

I've updated my tracking of Australian government and council Twitter accounts and found that the roughly 920 accounts I track have sent in total 1.47 million tweets.

Given there's some accounts that have closed down which I no longer count and probably a few more I've missed, I'm comfortable that Australian governments have now sent approximately 1.5 million tweets.

This represents explosive growth. It took 63 months (from November 2007 to January 2013) to reach one million tweets, but only 11 months to get from one million to 1.5 million.

The next half a million is likely to take even less time - I expect we'll reach it some time in July 2014 (and will report back so you can see if my prediction is correct).

But who's tweeting?

I'm glad you asked.

However the top ten most active, by tweets, followers, following and by age are below, followed by the number of tweets divided into category, location (state) and jurisdictional level (national, state/territory and local).

You might be surprised who's who in the roost.
