Leaders of the Australian Greens

There are Leaders of the Australian Greens (Greens) at the federal level, as well as in the several member parties which make up the confederation of the Australian Greens.

Background
On Saturday 12 November 2005 at the national conference in Hobart the Australian Greens abandoned their long-standing tradition of having no official leader and approved a process whereby a parliamentary leader could be elected by the Greens Parliamentary Party Room. On Monday 28 November 2005, Bob Brown – who had long been regarded as de facto leader by many inside the party, and most people outside the party – was elected unopposed as the Parliamentary Party Leader.

Most of the Green parties which have joined the Australian Greens do not have a formal leader, and instead they have a shared leadership structure. However, Tasmania, Victoria, and the ACT, have adopted singular leadership structures into their party.
