A Sydney man charged with stabbing two police officers at a service station south of Newcastle yesterday has been refused bail after apologising for his alleged actions.

Oliver Scales-Copeland, 25, fronted Newcastle Local Court today in a blue jumpsuit with two black eyes and other facial bruising.

The 25-year-old expressed remorse for the alleged attacks at a Toronto service station where he is accused of stabbing one police officer in the leg, and another in the hand.

The two senior constables used capsicum spray and a baton to try and disarm him before firing a number of shots.

"I do apologise for what happened and I do regret it," Mr Scales-Copeland told the court today.

"By no means do I have any intent to repeat what I have done."

Mr Scales-Copeland was detained at the service station with the help of witnesses who were doing court-sanctioned community service work.

He has been charged with two counts of wounding with intent to resist arrest, destroying property and common assault.

The police officers' injuries are not life-threatening.

Mr Scales-Copeland represented himself in court and appeared confused when Registrar Jane Bourne first read the charges out.

"These are very serious offences and you have to justify to me why you should not go into custody, do you understand?" Ms Bourne said.

Mr Scales-Copeland asked for the charges to be read out again before shedding light on what allegedly happened.

"The destroy property, you mean the car tyre, I accept I did that," he said.

"[But] basically I feel like I can get my life back on track without damaging any person or any property."

The registrar said he had failed to show cause in his case and that bail would be refused, at which point Mr Scales-Copeland became emotional.

"Oh God, please don't do that, I don't need that," he said.

The case has been adjourned to Toronto Local Court tomorrow.
