Federal National party leader David Littleproud has welcomed opposition leader Peter Dutton's announcement on Wednesday the Liberal Party will oppose the Voice to Parliament.

The National's were the first major party to announce their stance against the Voice in November where Mr Littleproud said he and his colleagues "don't believe that this will genuinely close the gap".

Speaking to reporters in Toowoomba on Wednesday he backed the outcome from the Liberals party room meeting and Mr Dutton's suggestions that the Voice threatens to have adverse effects.

"Unfortunately, sadly, I believe this (the Voice) has more potential to divide our country rather than bringing it together," Mr Littleproud said.

"The Nationals have said that from the start. We welcome the fact that the Liberal Party have got to this juncture as well.

"It's important now that the Australian people understand exactly what the Australian government is asking them to sign up to."

Mr Littleproud suggested the Nationals would be open to a negotiated outcome.

"If the Prime Minister wanted to be constructive, he'd sit down and rework this. And that's, that's now in his court. That's an opportunity for the Prime Minister to show the leadership to bring the country together," he said.

At the time of the Nationals' announcement in opposition to the Voice last year, Mr Littleproud claimed his party's consultations with Indigenous communities presented concerns over a national body.

Both the National and Liberal MPs have spoken in support of a redirection towards a regional and community-based model.

"The solution lies within a bureaucracy that's taken out of Canberra, and… with a local council and local Elders in each town - each Elder in each town devising their own program," Mr Littleproud said.
