Senator BRANDIS (Queensland—Deputy Leader of the Opposition in the Senate) (14:00): My question is to the Minister representing the Minister for Climate Change and Energy Efficiency, Senator Wong. I refer the minister to the evaluation by the firm Hall and Partners Open Mind, relied upon in the ANAO audit of the multimillion-dollar carbon tax advertising campaign, which found that the effectiveness of the campaign was 'disappointing' and that: 'There was limited acceptance of key messages related to carbon pricing and household assistance.' Does the minister accept the findings of the independent evaluation upon which the ANAO report relied, that the $31½ million campaign is a disappointing failure?
