Premier Dominic Perrottet is confident his push to reform stamp duty for NSW first home buyers will pass parliament, despite the bill facing significant hurdles.
The state government on Wednesday introduced the bill, which would give first home buyers a choice between paying an annual land tax or a lump sum of stamp duty.
Mr Perrottet says the opt-in trial, for homes under $1.5 million, is objectively good policy and should be put to a vote in parliament without delay.
He believes the bill will pass because it provides first home buyers with options.
"This is great legislation that makes a real difference to people's lives," he told reporters on Wednesday.
In the 24 hours since the policy was announced, some 10,000 people had accessed a calculator which checks whether first home buyers would be better off paying land tax or stamp duty.
The government wants a trial in place by January, although some crossbench MPs are uneasy about the speed of implementing such major reform.
The proposal is vehemently opposed by Labor, which has labelled it a "forever tax".
The premier accused the Labor Party of standing in the way of young Australians trying to achieve "the great Australian dream" of owning their own home.
Labor believes the tax reforms could cause house prices to rise and push more first home buyers out of the market.
Shadow Treasurer Daniel Mookhey says the government should take the reform to the next election, and believes it will be voted down in parliament.
The Greens, One Nation, Shooters, Fishers and Farmers and independent members of the crossbench are meanwhile seeking an inquiry to scrutinise the plan.
Greens MP Abigail Boyd believes the proposal needs close scrutiny, stressing any reform must be equitable and well planned.
"You can't rush through a reform as important as this one - it needs adequate thought and consultation to get it right," Ms Boyd told AAP.
The reform is supported by One Nation's Mark Latham, but he is also pushing for the details to be analysed in parliament before it goes to a vote.
Shooters, Fishers and Farmers Leader Robert Borsak says the goal posts have been moved on the reforms and more analysis is needed.
"I don't know what the legislation is about now - it's changed a lot since Perrottet was treasurer," he told AAP.
"This is a new tax that the government keeps dressing up."
It had the potential to become a long-term new growth tax, which his party would reject.
Independent MP Justin Field has not yet decided whether to support an inquiry and says questions remain over whether the issue could be scrutinised within a tight window.
"Broadly I'm supportive of the reform but it is major reform," he said.
"The parliament should be treated with more respect.
"The government has watered this down to such an extent ... that it may no longer achieve the shift from stamp duty to land tax they wanted to achieve.
"It affects so few people."
