Campbell was the chief orchestrator of the Titans' slashing left edge attack, producing three try assists in a 15-minute first-half period before putting the game out of reach with a try of his own midway through the second half.
The move to five-eighth continues to pay dividends for Campbell and the Titans, as his rookie halves partner Zane Harrison continues to prove he belongs in the top grade.

The 20-point victory secured Josh Hannay his maiden back-to-back win as Gold Coast coach, with the Titans achieving the feat for the first time since March last year.

The Titans responded to an early Tyrell Sloan try almost immediately, when a 50-metre long-range play was capped off by Dragons-bound winger Phil Sami.
An almost identical try followed four minutes later when Campbell laid one on for centre Jaylen De Groot.
De Groot's second try followed in the 26th minute when Campbell and the Titans made short work of the Dragons' right edge yet again.
A Kyle Flangan try made it interesting for the Dragons just before halftime, but two Campbell penalty goals and a try to Oliver Pascoe pushed Gold Coast further ahead after the break.
Campbell confirmed the result and a memorable performance by strolling over untouched midway through the second half.
