Friends and family converged on Tom Clyburn Oval - the football ground where Chris had played so many games in the past - for the public memorial service to the 27 year old who lost his life in the Rozelle blast on September 4.

The region's public tributes continued the following day, when thousands at the Central West Country Rugby League Group 10 Grand Final in Cowra paused for a minute's silence in honour of Chris.

His father Ross told those quietly gathered before the family on Saturday morning Chris would have been chuffed about the fuss being made about him, the number of messages received and the number of people who attended the service.

He said it also gave the family strength.

His mother Liz said she would not allow anger to cloud this moment.

"The last thing he ever did was send a message at eight minutes past four on the morning of Thursday September 4 saying 'I love you'," Mrs Noble said.

She told the crowd they should not have had to have been there farewelling Chris.

"There are no words to describe the distress and anger that we are feeling but I won't allow this tribute to Chris' life to also be taken away from us through the expression of this anger," she said.

"I will just be eternally grateful not more lives were lost on September 4."

Mrs Noble said she had tried so hard to keep her children safe and out of trouble growing up.

"Chris was tough and strong, bouncing back from a couple of severe illnesses in his childhood," she said.

"He was so strong I fully expected him to walk out of last week's situation."

His brother Michael said Chris was his best mate and he was sorry he wasn't there on that Thursday morning to protect him as he had always tried to do.

"Other than family there was nothing more important to Chris than his mates," he said.

"On weekends he would be travelling across the country for a rugby game with Canowindra or Drummoyne, American football with the Lions in Western Sydney, back in Orange for a night or in Canowindra with his mates."

His sister Kate said as his baby sister Chris had always been fiercely protective of her.

"It's a credit to him the amazing number of people here today who knew and loved Chris or who have been affected by him in some way," she said.

Her father echoed her words.

"We will miss Chris so much but he has a legacy that forever will be entrenched in our hearts and minds."

Chris Noble - along with Bianka and Jude O'Brien - died in the blast that tore apart a convenience store and apartments above.

Forensic investigators and Fire & Rescue NSW officers are still examining the crime scene to help solve the crime.
