The Narwan Eels have secured their first premiership trophy since their return to the Group 19 competition.

After coming close twice with two runners-up efforts in A-grade in 2017 and reserve grade in 2018, the Eels managed to topple reigning reserve grade premiers Moree Boomerangs in Sunday's grand final.

Narwan rocketed out to a 12-nil lead with Jo Green and Fletcher Strong crossed for tries in the opening 10 minutes, Jordan Moran slotting the extras before Moree mounted a comeback.

The lead changed twice more in the first-half with Green grabbing his second.

The Boomerangs held a 20-18 advantage at the break.

It took nearly 10 minutes for the first try of the second stanza to be posted with Duane Button bustling his way over.

Moree took back the lead but the rest was all Narwan with James Ahoy, Strong and Charlie Ahoy crossing to seal the 38-24 victory and the title win.
