Nyunggai Warren Mundine has called for reforms to the NSW Liberal Party after winning over the local members but not the state branch's Central Committee in a preselection battle for the Sydney seat of Bradfield.

The anti-Voice campaigner and prominent Indigenous businessperson lost the vote to Gisele Kapterian on 18 January.

Ms Kapterian secured more than 200 of votes, ahead of Mr Mundine on 171, with cardiologist Michael Feneley capturing 16.

Mr Mundine, a Bundjalung, Gumbaynggirr, Yuin and Irish man, has lived in the seat of Bradfield for over a decade and told Liberal members he has "demonstrated courage to fight for my convictions" and is "not beholden to factions or people behind the scenes".

"With me, what you see is what you get," he wrote in campaign material, arguing he was "uniquely positioned" to reach voters who haven't voted Liberal before in Bradfield.

Days after the vote Mr Mundine told National Indigenous Times it had been a "very short" campaign.

"I was overseas when (MP for Bradfield) Paul Fletcher pulled the plug… So, within two days, we had to organise ourselves. We had to get applications in, everything sorted, and then go through a process of reviews, nomination, review committees, etc, and also then get a team together, so within eight days… we pushed it right to the line and just missed out on winning. We won the local vote, we just lost it in the delegates from the Central Committee. So that was the problem," he said.

Mr Mundine said the democratic method should reflect the will of the local people.

"We have an administrator in control of the New South Wales Division at the moment, and they're going through a constitutional review, and we would argue that the locals are the ones who get to pick their representatives," he said.

"We'd like to see that very clearly… and there are other major issues that that we need to deal with within the New South Wales division, because at the moment, it's open to factional leaders being able to play their games with it.

"There's a whole lot of people, everyone says 'you'll be great candidate, you should be in the Senate, we should get you in this seat, we should get you into that seat'. An opportunity has arisen and then they roll in, the factional leaders of the wets (moderate Liberals) decided to roll out their big guns. And even with that, we were able to nearly knock them off in a really short campaign process."

Mr Mundine said despite the setback he was determined to see a change of federal government this election.

"My job now is to work hard, and I'll be traveling across Australia and in New South Wales and Queensland and other states to get Dutton into government, and I will, because this government is the worst government that I've ever seen," he said.

"They stuffed up the Voice campaign. They've just abandoned Indigenous Australians, because what are their policies?

"We have a cost of living crisis, we have Jewish people in Australia now living in fear while their preschools get burnt, houses and their cars have been attacked.

"My first priority is to do that (help the Coalition win the federal election), and then from there, I want to work with the administrators to reform the New South Wales branch, because you don't get an administrator put in unless you've got big problems."

Mr Mundine said he had many plans for the longer-term future.

"I am in the business world, dealing with my mining arrangements, also with the CIS (Centre for Independent Studies)," he said.

"And yes, in the political sphere, I will be pushing for a bigger role within the Liberal Party."
