Sixteen years ago, on this day, April 13th, Bob Brown announces he’s stepping down…
The leader of the third force in Australian politics announced his resignation from parliament on Friday, but said his party would maintain its support for prime minister Julia Gillard’s fragile minority government.
Bob Brown, 67, announced his resignation as leader of the Greens and said he would leave the Senate in June after 16 years to “make room for renewal” in the leftwing environmental party.
Brown, who has led the party since its inception in 1992, is Australia’s first openly gay federal parliamentarian. An opponent of the Iraq war, he came into the spotlight in 2003 after being banned from parliament for 24 hours for heckling the US president George W Bush.

The amount of carbon dioxide in the air was roughly 394ppm. As of 2026 it is 428ppm, but check here for daily measures.
The broader context was that Bob Brown had been fighting for peace and ecological sanity for a very long time, and in some of the most hostile places in Australia that you could do that – namely Tasmania and parliament.
The specific context was that after the 2010 election the Greens had held the balance of power, and Gillard’s minority government was forced to institute a carbon price, the so called Multi Party Committee on climate change, and with this done, Bob Brown could announce a very well-deserved retirement from formal politics.
What I think we can learn from this is that there are some people who are particularly well. They have wonderful qualities in terms of being able to rally others, serve as a focal point for other people’s projections and just to also do the work .
What happened next: Bob Brown has continued his activism, sometimes with more success, sometimes with less. I would say the 2019 effort in Queensland was fairly ill-judged, but I don’t think that the Shorten Labor lot would have gotten up anyway. There is a documentary about Bob Brown about which I have very mixed feelings, which are distinct from Brown himself, who, by all accounts and by all reckoning, is a very very admirable character.
