They then held on as former Bronco Kurt Baptiste bagged a double of his own to ensure some anxious moments for the hosts.The Raiders arrived at Suncorp Stadium full of confidence with a top-four berth in sight if they nabbed a fourth straight win.
But former ladder leaders Brisbane had other ideas.
Broncos captain Corey Parker ran out for his 336th NRL game, equalling Brad Fittler on fourth on the all-time games played list.
And it seemed nothing was going to stop him from celebrating the milestone, even fending off teammate Anthony Milford on his way to opening the scoring in the 25th minute.
Boyd then recovered from an early neck complaint from a suspected crusher tackle to beat Canberra halfback Aidan Sezer not once, but twice in four minutes - 30th and 34th - to give Brisbane a healthy 18-0 halftime buffer.
He bagged his hat-trick when he crossed in the 44th minute, handing Brisbane a 24-0 lead as alarm bells sounded for the visitors.
However, the Raiders were not done with yet.Baptiste's double (59th, 77th) and a Blake Austin try with 14 minutes left kept Brisbane honest.In another worry for the Broncos, the hosts also lost backrower Alex Glenn to a suspected shoulder injury by halftime.
