Young Broncos Kotoni Staggs, Tom Opacic and Jonus Pearson all scored as a powerful Redcliffe side brought Tweed Heads' run of six straight wins to a screeching halt.
While Redcliffe was at close to full strength - forced to play former NRL centre Mosese Pangai off the bench - Tweed were without a host of key players.
The Intrust Super Cup's leading try-scorer Brayden McGrady had an ACL injury confirmed just a week after he signed for the Penrith Panthers, while Gold Coast Titans-contracted players like Leilani Latu and Konrad Hurrell were unavailable.
To make matters worse, star pivot Kane Elgey was sin-binned in the 55th minute.
The 'Ferrari' Jonus Pearson opened the Dolphins scoring account early in the third minute after a cut-out ball from the fullback Tony Tumusa, bringing the momentum from last week's win.
It was fast paced, end-to-end football that had both teams looking to complete their sets while maintaining an attacking advantage.
Tweed had a few opportunities early to open their scoring account, with back to back sets in their half, however Redcliffe's defence was too strong.
A strong run from Dolphins prop Sam Anderson put the hooker Jake Turpin into good field position to score on the 20th minute. It wasn't long after that Turpin was assisting the man outside him, Staggs, who burrowed down to score in the 24th minute.
Mogg was full of praise for his young players, who have recently returned from injury or duties with the Brisbane Broncos.
"They're all great players, and I think Jake Turpin, who broke his ankle in Round Two, was really good too. It was a real credit to him, he's worked really hard – he played 30mins straight tonight, and I thought he was really good for his first stint since round 2," he said.
Tumusa was able to extend the home side's advantage in the 27th minute, backing himself for a four-pointer close to the line.
Tweed weren't out of the half – a few penalties put the away side into good field position to score and five minutes before the end of the first half, second rower Lamar Manuel-Liolevave put the 'Gulls on the board, going into the half 6-24.
It was the Seagulls who opened the scoring in the second half, after a quick offload to the five-eighth, Lindon McGrady, maintaining their momentum from the first half.
Throughout each set, the Dolphins appeared to be confident in their ball control, something Mogg said stems from the overall performance of the team.
"We have lots of different combinations going on in our footy team, different halves, different spines, different second rowers, and tonight we had different centres and wingers."
A line break and creative play from Staggs in the 61st minute saw winger Jeremy Hawkins score for the first time in the night.
The Seagulls had a late run, with centre Kurt McDonald scoring in the 72nd minute, however it wasn't enough to stop strength of the Dolphins.
While it was an overall team performance that saw the home side take out the win, Mogg noted his forwards for their efforts.
"I think Sam Anderson is in good form, James Taylor is playing really well, and Nathan Watts is really starting to have some consistency. We lost two back rowers tonight too."
The Dolphins head to Bishop Park next weekend to play the Norths Devils – a game that Moggs said the team just has to keep improving for.
Tweed Heads is away to the Central Queensland Capras at 6pm Saturday.
