Raymond Terrace Magpies upstaged minor premiers Waratah-Mayfield with an 18-12 victory in the Newcastle and Hunter Rugby League C-grade grand final at Kurri Sportsground on Saturday.
The Magpies had been beaten by the Cheetahs in three of their four meetings so far this season, but bounced back in the decider.
In B-grade, Cessnock Cutters completed a fairytale debut season with a 34-26 defeat of Tea Gardens.
The Cutters, who were formed this season, scraped into the finals by finishing fifth and preceded to win four consecutive sudden-death finals in four weeks.
Cessnock raced to a 22-4 half-time lead, and while the Hawks claimed two late tries to ensure a nervous finish the Cutters were never headed.
The A-grade showpiece of the day saw another fifth-placed side claim grand final glory, with Cardiff edging out Windale 24-20.
In D-grade Karuah Roos claimed first points but were eventually overpowered 25-18 by minor premiers Williamtown Jets.
