A court order preventing major demolition works at Sydney's Allianz Stadium may be extended by a judge to allow an appeal in NSW's highest court.

A community group's bid to stop the controversial demolition of Sydney's Allianz Stadium is heading to NSW's highest court.

Local Democracy Matters on Thursday announced it would appeal to the NSW Court of Appeal after the Land and Environment Court threw out its challenge to halt the $730 million project to rebuild the city's biggest rectangular stadium.

Justice Nicola Pain on Wednesday dismissed a bid from the group and Waverley Council that claimed Planning Minister Anthony Roberts had failed to consider "design excellence" before approving the project.

She also said the demolition proposal had been publicly exhibited for the required period of time and the government had considered soil contamination issues.

The appeal will be heard on Monday, but Justice Pain's temporary injunction preventing major demolition works is due to be lifted at 5pm on Friday.

However, she could extend the order with a ruling due on Friday morning.

"Regardless of what has happened this week, the case will go on and the argument will be made not just on the streets, not just at the ballot box, but also in the courts," Greens MP David Shoebridge told reporters on Thursday.

Local Democracy Matters spokesman Chris Maltby, who is an IT specialist for the Greens, said it would be an outrage if the bulldozers were sent in before Monday.

"If the government does proceed like that, it says everything you need to know about how they've carried out this project," he said.

Premier Gladys Berejiklian was asked numerous times on Thursday whether her government would proceed with hard demolition works if the court injunction was lifted but refused to give a direct answer.

Instead, she told reporters "it's business as usual".

"We get on with delivering all the projects we've said to the community we are going to build," Ms Berejiklian said.

Opposition Leader Michael Daley has called for demolition works to be delayed until the state election.

"There are 16 days to go until the election. There is no reason why this stadium should be demolished as it is," he told reporters.
