The Raiders have handed the Sea Eagles their first loss in five weeks after producing a remarkable second-half comeback on Friday night to win 26-24 at 4 Pines Park.
Behind by 20 points midway through the first period and facing an 18-point deficit early in the second, Canberra's unlikely surge began on 53 minutes when returning captain Elliott Whitehead scored the first of his two tries.
It ended with Hudson Young's try three minutes from full-time, with the Raiders surviving two late charges from the Sea Eagles and an attempted two-point field goal from Daly Cherry-Evans with seconds left on the clock.
