The federal election result remains too close to call, but a strong flow of independent and minor party preferences is likely to go to the coalition, a new study shows.
The Australian Institute for Progress study released on Monday gave Labor a 51-49 two-party preferred lead.
But 24 per cent of voters supported independents or parties other than Labor and the coalition.
It also found Labor and Greens voters had starkly different priorities to coalition and independent candidate supporters.
In the AIP's June Omnibus poll - using an online panel via Leximancer - climate change, education, refugees and health were rated as the key issue for Green and Labor voters.
A strong economy, border protection and combating terrorism were rated priorities for coalition and independent voters.
The study found 70 per cent of non-Greens minor party preferences would go to the coalition.
Asked whether they would support the same party in both the lower house and Senate elections, 72 per cent said yes, while 17 per cent said no.
AIP executive director Graham Young said quantitative data picked up in the study showed voters didn't trust the major parties, which added to the tightness of the July 2 race.
One respondent said: "Both major parties are proposing band-aid solutions to systemic problems in tax, education and health. No one is proposing the radical reform of these systems that we need."
Another added: "I believe they play a very important role and remind the major parties that they cannot ride roughshod over the people, dispensing with election promises that no longer happen to suit them."
