Julian Strangio had an eerie feeling when he picked up a late-night phone call 13 years ago.

"You always know it's going to be bad news at that time," he told reporters on Monday.

The news that his brother, Paul Strangio, had been shot dead in Sydney's west has stayed with him ever since.

More than a decade on, no arrests have been made and the cold case of a beloved father, brother and grandfather remains a mystery.

Police have launched a fresh appeal for information on the murder of Mr Strangio, offering $500,000 for information that leads to the conviction of the 42-year-old's murderer.

The night of the shooting, police believe three people forced their way into the Glenmore Park home before firing and killing Mr Strangio.

NSW Police homicide squad boss Virginia Gorman said the attack was not random.

"Somebody knows something," she said on Monday.

"There's three people, everyone can't possibly keep a secret."

For the family left behind, the wait for answers has been frustrating.

"They've taken a brother, father, grandfather, they've taken away our Christmases," Julian Strangio said.

"He won't watch his grandkids grow up, what we have now is just memories."

Police were called to the Glenmore Park home on February 6, 2010, where they found Mr Strangio dying from gunshot wounds.

Two others were also present and helped police with their inquiries at the time.

Strike Force Goodier was established to investigate the murder but made no arrests or charges.

Anyone with information on Paul Strangio's murder should contact NSW police.

Kalyn Ponga concedes he must keep himself on the field to win back his Queensland No.1 jersey after overcoming multiple head knocks to help Newcastle to a 28-18 NRL victory over Manly.

In his first game for the Knights since being axed for State of Origin I, Ponga overcome a shaky start to look dangerous in every touch at fullback and set up a try in the Knights' win.

Crucially, he was able to bounce back from three head knocks to play the 80 minutes after Queensland selectors admitted Ponga's history of concussions and a head injury assessment last week played a role into his Origin snub.

Ponga insists the Maroons decision to leave him out for Adelaide had not played on his mind in the match, nor did it influence his move from five-eighth to fullback.

But he is well aware the only way to get back into the Queensland side is to string matches together without concussion scares.

"I just have to play games, I can't worry about (selection)," Ponga said.

"I am fortunate that today I had a couple and obviously no effect. I felt fine. It is part of footy and a part of my game. I can't worry about them.

"I can't go into games worried about that. I just need to move on and do my role and play good footy."

Ponga said he was disappointed by Slater's decision to leave him out of Game I after he starred in last year's decider, but he "accepted and respected" his non-selection.

After throwing an early intercept pass and kicking a dropout that failed to go 10 metres that helped send Manly out to an 8-0 lead, Ponga bounced back into the game at McDonald Jones Stadium.

He busted four tackles, provided several half breaks and put hat-trick hero Greg Marzhew over untouched after a Lachlan Fitzgibbon offload to level the scores at 14-14 after Newcastle trailed 14-10 at the break.

"I probably felt I used my eyes a lot more at the back," Ponga said.

"Being at fullback, being able to see both sides of the rucks. I felt freer in that sense."

Dane Gagai also had several strong runs in the win after being dropped by the Knights, while Daniel Saifiti was one of their best forwards after being overlooked by NSW.

The Knights squandered several chances in the first half, and allowed Manly back into the game at 18-18 with 18 minutes to go when Jackson Hastings offered up an intercept pass for Jason Saab.

But when Tolutau Koula was sin-binned for a high hit on Ponga with 15 minutes to go, the Knights were able to take charge against a Sea Eagles outfit missing Daly Cherry-Evans, Tom Trbojevic and his brother Jake.

Knights hooker Phoenix Crossland scored under the posts after a scrappy play with Koula off to put Newcastle back in the lead, while a length-of-the-field effort from Dom Young sealed the game.

Manly were gutsy given the players they were missing, and scrambled well to save several tries before the time without Koula cruelled them.

"I didn't think it was a sin-bin," Seibold said.

"It was a harsh call, but that's not why we lost the game.

"I was super proud of the guys today. We were brave, really brave. We had five or six try-saving tackles.

"They kept turning up for each other out of position. It's disappointing because of the effort they put in."

Canberra forward Corey Harawira-Naera is hoping to return to the field as soon as possible after being discharged from hospital following his mid-game seizure.

Harawira-Naera says he is "on the mend" but "not in the clear yet" and will undergo further tests to get to the bottom of the frightening incident at Sydney's Accor Stadium.

Shortly after taking a hit-up in the second half against South Sydney on Saturday night, Harawira-Naera appeared to become disoriented and fell to the turf.

The match stopped for more than 10 minutes as medical staff rushed onto the field and attended to the New Zealand international, who had begun convulsing.

Harawira-Naera was conscious and responsive by the time he was transported from the field in a medicab amid a standing ovation from the crowd.

He was taken by ambulance to Westmead Hospital with his sister, who was a spectator at the game.

The New Zealand international was discharged about 3:30am on Sunday and shared a video update on his condition about eight hours later.

"I'm back on the mend, not in the clear yet but we'll get some more scans and sort it out," Harawira-Naera said.

"Health comes first but I'm obviously hoping to get back on the field as soon as possible as well."

Harawira-Naera thanked those who showed support following the medical episode.

"I've been pretty fortunate to receive a lot of messages about what happened last night," he said.

"I'm doing a lot better now, so love to you all."

No player harboured more concern for Harawira-Naera on Saturday night than teammate Albert Hopoate, who roomed with the second-rower for three years.

The pair are close mates, FaceTiming or catching up most days, and the Raiders winger was visibly distressed when Harawira-Naera went down.

"Obviously it was pretty scary at the time," Hopoate told AAP.

"You don't expect anything like that to happen, especially in a game. There aren't many words."

Canberra captain Jarrod Croker abandoned all thoughts of the contest as his teammate lay on the ground.

"For that whole period, I don't think anyone was thinking about football, to be honest," he said.

"Everyone was just looking out for Corey and doing whatever we could."

Raiders coach Ricky Stuart praised both his players and South Sydney's for rushing to Harawira-Naera's side after he fell.

The players encircled the 28-year-old to give the medical staff privacy as they worked on him.

"That's when you see the real character of these footballers," Stuart said.

"When one of the boys go down, it doesn't matter what team he's on, everyone got around the fact that it was a serious situation.

"There was a lot of care out there for him. That's appreciated by all our players and club, how the Souths boys handled it as well.

"No one likes to see those serious types of scenes."

The Raiders regrouped after Harawira-Naera left the field and vowed to keep playing in his honour, eventually triumphing 33-26.

"Jarrod Croker, he's our leader and Jamal Fogarty, those two are pretty good leaders and they always know what to say in moments like that," Hopoate said.

"We got in a huddle after that and said we'll do it for Corey, and we did."
