I used to go to some of the Lowy Institute lunchtime speakers program. Now I down load the talks onto my ipod and listen when I am the gym. This way I get to experience all the talks. I highly recommend them.

The Lowy Institute is an independent international policy think tank. Its objective is to generate new ideas and dialogue on international developments and Australia’s role in the world. Its mandate is broad. It ranges across all the dimensions of international policy debate in Australia – economic, political and strategic – and it is not limited to a particular geographic region.
The Institute has two core tasks:
To produce distinctive research and fresh policy options for Australia’s international policy.
The Institute seeks to throw fresh light on issues of relevance to Australia through rigorous research, and then to generate workable policy ideas. The Institute also seeks to contribute to the wider international debate. We believe Australia can make a significant contribution to the global dialogue.
To promote wide discussion of Australia’s role in the world.
This is the Institute’s other vital task: to provide an accessible and high quality forum for discussion of Australian foreign policy and international relations, through debates, seminars, lectures, dialogues and conferences.
