The figures come from the latest Australian Election Study from the Australian National University and Griffith University.
In a warning to the major parties, the study noticed a decline in voter loyalty.
“Voters are now less ‘rusted on’ to the major political parties and becoming more independently minded in their political choices,” Professor McAllister said.
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.
