Julia Gillard’s Labour government has has a difficult couple of months over the issue. Gillard had to deal not only with rabid opposition from Tony Abbott’s Opposition but her own U-turn.

I wonder if anybody will be watching Oz when the negotiations begin in Washington over the fiscal cliff (assuming Obama wins, touch wood, finger rosary, spin prayer wheel, slay chicken).
