With the Independent Senator, Nick Xenophon, the National's Senator Barnaby Joyce and Labor Senator, Mark Arbib, on Q&A this week, we only have one thing to say…welcome the Senate. Joining them were journalist and author of "Inside Kevin 07", Christine Jackman, and Chief Executive of the Australian Industry Group, Heather Ridout.

This week's Q&A had something for everyone: Peter Garrett, the Minister for the Environment, Heritage and the Arts went head to head with the Shadow Minister for Veterans' Affairs Bronwyn Bishop. Joining them were the Chaser's Julian Morrow, the Director of the Indigenous Law Centre at UNSW, Megan Davis and a columnist for the Australian, Imre Salusinszky.
