You are one election behind - did you forget a different labor PM made promises before the 2010 election?
2007 was Rudd's campaign. That's old news and his dismantling of the Pacific Solution has left us with thousands more arrivals which have overcrowded our facilities onshore. That policy clearly did not work.
Gillard ran the 2010 election campaign with the promise of no carbon tax and she also promised to stop the boats.
She has NOT delivered on either major policy promise.
