Q&A has a standard formula for its panelists: 3 left leaning, 1 right leaning and 1 wildcard. Considering that a majority of the Australian public voted for an Abbott government, that makes Q&A is a left leaning program from the perspective of the Australian audience.
I do agree that 7:30 Report and ABC News is much more unbiased these days, besides the fact that the Coalition ministers do tend to get a harder time in interviews.
