Opposition Leader Tony Abbott is looking more likely to be able to make good on his oft-repeated assertions to scrap the carbon tax should the Coalition win government in September.

Analysis of voting trends shows that should the present pattern continue to the election, the Coalition would effectively control both houses of parliament, making it powerful enough to repeal the carbon tax.

While Prime Minister Julia Gillard has previously claimed Mr Abbott will not have the numbers to honour his ''blood pledge'' to scrap the carbon tax, an analysis of Senate seats up for re-election reveals a majority will likely fall into conservative hands.

Senior lecturer in politics at Griffith University Paul Williams said ''there should be no electoral or numerical obstacles to Tony Abbott repealing the act early in his first term''.
