protocol, setting "voluntary aspirational emission reduction targets" and introducing a carbon emissions trading scheme by 2012. Labor pledged a $4.7 billion fibre-to-the-node broadband network. On 7 June in a speech promoting the government's handling of the economy, Treasurer Peter Costello recalled the learner driver slogan of the 2004 election: "This [the economy] is like a highly engineered racing car and I tell you what, I wouldn't be putting an L-plate driver in the cockpit at the moment". August 2007 saw, for the first time during an election campaign, a 0.25-point interest-rate rise to 6.5 per cent by the Reserve Bank, the sixth rise since the last election in 2004. Labor used the news to argue that the Coalition could not be trusted to keep interest rates low, while Costello argued that interest rates would be higher under Labor. In November 2007 interest rates were raised for the sixth time since the 2004 election, to a 10-year high of 6.75 per cent. In response to Labor criticism of the government on the rate rises, Howard stated in August 2007 "[Rudd] can scour every transcript, and I will make them available, of every interview that I gave during that election campaign and he will find no such commitment. During October 2007 Immigration Minister Kevin Andrews's decision to cut Australia's refugee intake and expressing public concern about Sudanese migrants was branded as racist.

Labor politician Tony Burke branded Andrews' decision as "incompetent". However, Andrew's actions were applauded by the former One Nation politician, Pauline Hanson. Andrews was accused of helping to fuel assaults of Sudanese. During the controversy one criticism was that Andrews justified his decision based on "concerns raised by the community", however no official report or inquest has been tendered, leading to the conclusion that any 'concerns' were both unofficial, undocumented and most probably belonging to a racially intolerant minority. The Howard government had before used the race card in an election year to distract the voters from its other failures. This was most significant in the 2001 election with the infamous Tampa affair, in which the government was badly trailing in the polls before vilifying middle-eastern "boat people". The strategy worked
