Unbeaten NSW/ACT clinched the Division 2 NAB AFL Under-18 Championships with a massive 119-point win over the Northern Territory on Sunday.

Queensland also showed its strength in the final round, completing the carnival with a 88-point win over Tasmania.

Will Setterfield reaffirmed his top-10 prospects with a 28-disposal display for NSW/ACT. The GWS academy product was excellent in the first half when the game was up for grabs, using the ball well and rarely flustered when in possession.

Ben Davis, the brother of Sydney Swan Abe, also booted four goals.

The NAB AFL MVP for NSW/ACT was Harry Perryman. Usually a midfielder, the 184cm prospect went to half-back and used his clean hands to great effect.

Fletcher Carroll spent his time in the middle and up forward, finishing with 26 disposals and a goal. His energy around the ball meant he was always dangerous.

Max Lynch, a 200cm ruckman, kicked two goals and showed he could thrive in attack. The Giants will have first dibs on him at this year's draft.

For the Northern Territory, Rohan Armstrong was the carnival MVP, adding another 21 disposals on Sunday. The left-footer was dynamic and played as a midfielder and small forward.

Lachlan McKenzie topped the possession count for his team with 27 and provided drive out of defence.

Ben Long, 18, was another significant contributor with 22 disposals and has already garnered interest from AFL clubs.

Gold Coast academy member Jack Bowes put in another brilliant performance to put forth his case to be drafted at No.1 this year.

Bowes finished with five goals and 20 disposals as Queensland ran out 18.11 (119) to 4.7 (31) victors against Tasmania.

The midfielder was his typical self, showing class and composure with the ball. He rested in the forward line and did much of his damage in attack.

Connor Ballenden also booted five goals for the Queenslanders. The 198cm Brisbane Lions Academy prospect will be eligible for the 2017 NAB AFL Draft and showed off his excellent set shots for goal, including drilling one from 50m out.

Another talent involved in the Gold Coast academy, Josh Williams, had a sparkling game. 

Defender Declan Watson was impressive off half-back. Standing at 194cm, Watson controlled the play with his intercept marking and consistently beat his opponents. 

Another member of the Suns' academy Brad Scheer was the top disposal-winner for the game, with 29 for Queensland.

For Tasmania, the most exciting prospect was 16-year-old Tarryn Thomas, who was named the NAB AFL MVP for the state.

His class and size (186cm) have him earmarked as one to watch for the future. Thomas will also play in the under-16 championships later this year.
