It's the biggest result for smaller players in Canberra in 100 years with experts saying it shows a slow decline in "rusted on" major party voters."Voters are now less 'rusted on' to the major political parties and becoming more independently minded in their political choices," Professor McAllister said."This trend has been driven by wider societal changes, such as the huge expansion of higher education, the turnover of generations, the rise of social media and shifting issue priorities."The other co-author of the study, Griffith University's Dr Sarah Cameron, said it wasn't enough for voters to fall out of love with major parties, they needed to have a viable alternative to shift their vote to.Dr Cameron and Professor McAllister's research also found less than one in five teal voters had previously voted for the coalition, with these people ideologically closer to Labor and the left of centre."
