The Deputy Premier, John Barilaro, has given a fresh indication that the government could wind back its policy to demolish and rebuild Sydney sporting stadiums, after he insisted “a final decision” still had to be made.

Mr Barilaro’s comments are at odds with the Premier Gladys Berejiklian, who was last week asked to guarantee she would pursue the controversial policy through to next year’s election.

“That is our intention, of course,” Ms Berejiklian said.

In response to opposition questions in Parliament, Mr Barilaro indicated on Thursday that the $2.5 billion policy was not a done deal.
