Minns won't knock NSW premier over ambulance treatment

A frazzled Dominic Perrottet has denied seeking special treatment when calling Health Minister Brad Hazzard after his wife fell ill and became "paralysed" in pain.

The response to the February 14 call dominated the premier's press conference on Wednesday as he repeatedly defended his actions that resulted in NSW Ambulance Commissioner Dominic Morgan organising a "low priority" ambulance to be sent to the premier's home.

Mr Perrottet said he rang wife Helen after an event and found she was "in immense pain, paralysed in bed and in tears" following a trip to the gym.

He called Mr Hazzard, who was in a car with Dr Morgan and a doctor, and sought advice from those in the vehicle.

"All I was aware of was that I'd spoken to the senior specialist, I had spoken to Dom Morgan, they said 'you need to go home. Go straight home and be with your wife'," the premier said.

He insisted he was completely transparent but would have to seek advice from NSW Health about media requests to view the ambulance call-out logs.

Labor leader Chris Minns took the premier's word that he received no special treatment, adding he didn't know how he would respond in the same situation.

"I'm not going to knock the premier for the decision that he made," he said.

"I am going to take issue with the government in relation to the performance in health."

The premier and opposition leader were also singing from the same song sheet after pre-election violence outside a Sydney church where NSW One Nation leader Mark Latham was due to speak about parental rights.

LGBTQI activists protesting against Mr Latham in Belfield on Tuesday night had bottles and rocks thrown at them and required the protection of police. Riot squad and other officers dispersed a crowd of about 250 people, NSW Police Superintendent Sheridan Waldau said.

"Violence in relation to democracy and elections has never been the hallmark of this country," Mr Minns said.

Mr Perrottet said it was "disgraceful".

"There is no place for violence in our state, full stop," he said.

Mr Latham accused the activists of provoking "the wild scenes at Belfield".

Those two issues took the shine off policies each leader spruiked before their final televised debate on Wednesday night.

Mr Perrottet returned to northwestern Sydney's Riverstone to underline how he would expand his signature First Home Buyer Choice scheme to include victims of domestic and family violence and buyers' second homes.

More than 2300 new homeowners have chosen annual land taxes over upfront stamp duty since the scheme passed parliament in November.

Labor took another jab at Sydney's toll road status quo, promising to publicise details of government contracts for NorthConnex and WestConnex, as well as capping tolls at $60 per week.

Ahead of Saturday's official polling day, a record number of voters have voted by post this election, with 540,208 applications representing 9.7 per cent of the electorate received by the electoral commission.

Mr Minns, who polls show is on track to win minority government, said the election would "come down to the wire".

"It will come down to an individual in a seat in NSW, who makes up their mind potentially at the last minute," he said.

"I just say to that person, (the coalition government's) best days are behind them, the most experienced people have left, we believe it's time for refresher."
