This week Opposition Leader Tony Abbott's got the chance to face the questions of genuine voters, live and unscripted. With polling day less than a week away Q&A returned to the Casula Powerhouse in western Sydney, a key regional battleground containing several marginal seats that may decide which side comes out on top in the election. The first question, from Rebekah Ruth Morrison, deplored the negativity of the campaign and invited Tony to outline the biggest reason why voters should elect him. Xenogene Gray challenged the Opposition Leader on his broadband policy before video questioner Fraser Tustian, from Thornleigh in NSW, asked Tony to imagine he was in an earlier century and having to choose between a national rail network and a national tram network. In response to a question on the school building program from Teresa Ragusa, Tony suggested a judicial inquiry might be needed to investigate waste and mismanagement.
