Support for recognition of Indigenous Australians in the constitution has dropped below 60%, according to an Essential poll released on Tuesday.
The poll of 1,006 respondents found 58% said they would vote yes in a referendum to recognise Aboriginal and Torres Strait Islander people in the Australian constitution.
The figure is a decline on the most recent poll commissioned by Recognise which found 63% in favour in May and a JWS Research poll in July which found 60% in favour of recognition and 59% in favour of a treaty.
The poll also found 61% of respondents disapprove of the government’s proposal to allow a single company to own all three of a newspaper, TV network and radio station in a single market.
It found 18% approve of the abolition of the two-out-of-three rule, 22% don’t know, and the majority of those that disapproved of the policy did so strongly.
The Essential poll found Labor leading the Coalition 52% to 48%, echoing a Newspoll released on Tuesday that had the same 52-48 result, albeit with a slightly higher Coalition primary vote of 39%.
It found continuing high support for voluntary euthanasia, at 68%, consistent with Essential polls as far back as 2010.
The campaign for constitutional recognition is entering a fragile period. Although recognition enjoys majority support, the referendum council has not approved a particular proposal to be voted on at a referendum.
Labor has said it would consider a treaty with Aboriginal Australians in addition to constitutional recognition, a proposal which led the government to accuse it of putting at risk “meaningful but modest” change in the form of constitutional recognition.
Asked to rate a series of issues on their importance, 75% of respondents to the poll said reaching a global agreement on climate change was important, compared with 62% for a banking and finance royal commission and 59% for a treaty with Indigenous Australians.
Issues which a majority did not consider important included a plebiscite on same-sex marriage (36%) and a referendum on a republic (34%).
The Labor financial services spokeswoman, Katy Gallagher, said the poll showed the government was “out of touch” on a bank royal commission because even 59% of Coalition voters were in favour, according to the poll.
