Strathdale-Maristians will represent Northern Rivers in the statewide Twenty20 competition after they won the Kookaburra Cup final on Sunday.
The Kookaburra Cup brings together all the T20 winners in the Northern Rivers zone and the Suns outclassed their opposition in Echuca.
In Sunday morning's semi-finals, the Suns gave Elmore a hiding.
Elmore won the toss and batted and were bowled out for 62 in 18.1 overs.
Matt Gilmour (20) and Aaron Juffs (17) were the only Elmore batsmen to reach double figures.
Strathdale star Sam Johnston had the remarkable figures of 4-3 off three overs, while Cam Taylor took 3-7.
The Suns needed just 28 balls to win the game after James Vlaeminck (31 not out) and Johnston (23) hit five fours and four sixes between them.
In the final against Moama, the Suns restricted Moama to 8-106 off 20 overs.
Johnston (2-15) and Ben DeAraugo (2-26) were the most successful bowlers in an even team performance.
The target was never in doubt after Johnston (23 off 14 balls) and Jack Neylon (44 off 29 balls) launched an early barrage of boundaries.
Taylor added 23 in the middle overs as the Suns eventually won by six wickets with more than six overs to spare.
Northern Rivers won their first round match of the Victorian Country Cricket League under-21 competition on Sunday.
Kyabram's Jesse Barker (109) and White Hills' Caleb Barras (30) batted well in Northern Rivers' score of 9-221 off 50 overs against Central Highlands at Newstead.
In reply, Central Highlands were bowled out for 196 in the 44th over.
Bendigo's Bailey Goodwin (4-27 off 10 overs) and White Hills' Jack Bourke (4-27 off 10 overs) did the damage with the ball for Northern Rivers.
Central Highlands would have lost by more had it not been for former Sandhurst batsman Darby Semmens (37 not out) and Declan Slingo (40) adding 67 for the final wicket.
The next game is against North East Country in Cobram next Sunday.
