LNP leader David Crisafulli’s long-awaited decision on the issue comes on the same day the Albanese government’s legislation passed the lower house of federal parliament.

“I have made up my mind: I won’t be voting for the voice to be enshrined in the constitution,” he told reporters on Wednesday.

“I note that the bill has just passed the lower house of parliament and I said I’d make my decision clear when I’d come to that decision.

“Having looked at the committee report, having looked at the prime minister’s contribution in Adelaide, I’m just not convinced that is the best mechanism to deliver changes needed.”

Crisafulli’s position echoes his federal counterpart Peter Dutton’s stance against enshrining a national Indigenous voice in Australia’s constitution.

The LNP leader said he would not campaign on the issue and would instead keep his focus on Queensland issues.

He said there were two main reasons why he has chosen not to support the voice.

“I’m not convinced that the body and the way it will be enshrined in the constitution, that there’s not a level of risk about its powers,” he said.

“There is a second reason though, and that is I don’t feel that a voice that is legislated wouldn’t be able to achieve exactly the same thing as one that’s enshrined in the constitution without that level of risk.”

Crisafulli said he was not convinced the constitutional body brought about by the voice would not undermine the power of federal parliament.

“In a democracy, I think every Australian wants to know that the parliament, the people who are elected, ultimately can be held accountable and if there’s a body that could override that, that is a real risk,” the LNP leader said.

He indicated the voice could be enacted through legislative changes instead of a constitutional referendum.

He said he would continue to fight and “stake his reputation on the line” for Indigenous communities ahead of next year’s state election, and asked people to take a considered position.

“I know there will be people who support my views, there’ll be people who disagree. I ask them to take the time to come to a considered position and do it in a respectful way.”

All state and territory leaders have thrown their in-principle support behind the voice including the sole Liberal, Tasmania’s Jeremy Rockliff.

Queensland Premier Annastacia Palaszczuk supports a constitutional voice, saying it would help Australia “move forward as nation”.

Crisafulli has previously defended taking his time on announcing his position.

He said in April that a lot of Queenslanders would be taking their time to make an informed decision, and “I’m one of them”.
