Moore, 19, who attended Kadina High School and Trinity Catholic College, was denied a try that would have put the Kumuls ahead 20-12 with the kick to come early in the second half.
England went on to win 32-22.
Referee Shayne Hayne ruled a forward pass – a decision that PNG coach Adrian Lam said had been devastating.
“It would have put us 10 points ahead if we had got the conversion as well,” he said.
“That really hurt but we hung in there. A couple more decisions going our way and it’s game on.”
Moore played junior rugby union and rugby league on the Far North Coast before joining Tweed Seagulls and then the Gold Coast Titans to play in their Toyota Cup Under-20 team.
The winger continued to impress. He was identified as an outstanding talent by PNG selectors and now many pundits are saying it is only a matter of time before he makes his NRL debut for the Titans.
Moore was not out of his depth on Saturday night against an England line-up that many believed would make short work of the Kumuls.
His positional play was sound and he stamped his mark early with a try-saving tackle.
The Kumuls head to the Gold Coast next to face New Zealand at Skilled Stadium on Saturday.
Their first-up performance is sure to attract many Northern Rivers fans.
An emotional Lam was still confident his team could cause an upset over the Kiwis or Kangaroos in
“Tonight we showed we are a young, courageous and spirited side and I couldn’t be prouder of the way the guys played,” Lam said.
“It was a little bit about getting some respect back from the world of rugby league.
“We obviously have a big task against New Zealand, and to be honest the past four weeks we have been planning to play and beat England.
“We entered the game truly believing we could win it and if we had a few of the 50/50 calls go our way who knows what might have happened.”
