Batting first, the Barramundis got off to a promising start with openers Tony Ura (21) and Anthony Vare (29) putting on a 52 run-opening-wicket partnership.
Then a steady fall of wickets saw the visitors slump to 6/119 in the 26th over when Charles Amini Jnr was dismissed for a quick-fire 28 runs.
Some fighting performances from Sese Bau (16), Kipling Doriga (28) and Jason Kila (24) took the score to 8/169 in the 39th over before an amazing rear-guard performance from Norman Vanua (50* runs off 40 balls) and Chad Soper (30* runs off 44 balls) took the score beyond 250.
