I move:

That the Senate—

  (a)   notes that:

     (i)   the Prime Minister (Ms Gillard) said in the 2010 election campaign that achieving harmonised occupational health and safety laws was her greatest achievement, and

     (ii)   harmonisation of occupational health and safety laws has not taken place; and

  (b)   calls on the Prime Minister to advise the Australian people, in light of this, if the carbon tax is now her greatest achievement.

The question is that the motion moved by Senator Back be agreed to.
