Nikolai Toport-Stanley says VAR got the decision right when Dimi Petratos was allowed to take his penalty again after Central Coast keeper Mark Birighitti came off his line.
A penalty was awarded when Giancarlo Galluifuco handballed in the box during Saturday's F3 derby.
Birighitti saved Petatros' first penalty, before VAR intervened and orded it to be retaken, which the Newcastle playmaker duly converted.
Jets defender Topor-Stanley feels it was the right call.
"Looking back it was the right decision," he said.
"He was clearly off his line and that’s what the VAR’s job is there to do."
The centre back believes Newcastle have work to do after their 1-1 draw with the Mariners.
"We’ve got a lot to improve on," admitted.
"But a solid performance I guess and something we can build on. We were fairly solid, but something was a little bit lacking."
The Jets host Adelaide United at home this weekend, their first home match of the new season.
The Reds have lost back-to-back games so far this season, but Topor-Stanley remains wary of them.
"We won’t be underestimating them at all," he said.
"It will be a tough ask but we’re looking forward to it. This is an opportunity for us to get three points."
