After charging out to a four-point lead at half-time, the Raiders U20's couldn't match it with the Broncos in the second half, going down 24-16.
Coach Brett White made one late change to the team for the clash, bringing in Logan Spaander to replace Kitione Vikash on the wing.
As has been standard in the first month of the season, the Raiders started relatively slow, but unlike past matches their defence held strong and repelled numerous Broncos attacks.
Instead it was the Raiders who scored first, with hooker Jarred Tuite crashing over to give the Raiders an early lead.
A defensive lapse allowed the Broncos to hit back moments later, with Payne Haas taking advantage of plenty of space to score near the posts.
Both teams continued to battle for an upper-hand, and it was Raiders captain Kalani Going who was able to break through just before half-time. A neat kick by Lachlan Cooper sat up perfectly for Going to score, giving the Raiders a 10-6 lead at the break.
It was the home side who came out much stronger in the second half, scoring three tries in quick succession to build a handy lead.
While the Raiders had a couple of good chances to get themselves back into the match, errors brought them undone on numerous occasions.
Harry Van Dartel continued his strong run of form by grabbing a late try back, but it was the home side who finished winners, 24-16.
The Raiders will return home next weekend to host the Parramatta Eels on Saturday at GIO Stadium.
