It was a weekend to remember for the Hawks' u15s and u17s teams, who posted dominant wins over Scarborough and Subiaco-Floreat respectively.
Subiaco-Floreat u17s won the toss and elected to bat first, losing early wickets to fall 3-13 as Cameron Sawatky made his mark with the ball.
Gosnells restricted Subiaco-Floreat to just 146.
Gosnells' Curtis Holmes was the pick of the bowlers, finishing with figures of 4-15 to earn himself the Player of the Match honour, backed superbly by team mate Cameron Sawatsky (3-19) and Aqeel Wahid (2-23).
The Hawks tackled the run chase with great confidence, cruising to a six-wicket victory.
Top scorer was Aqeel Wahid was outstanding at the crease with an unbeaten 45, closely followed by Daniel Smedley (39) and Clayton Stone with a well-made 27.
The Hawks u15s journey to the grand final was a tough task, after the side placed fourth after the home and away season and had to beat the top three sides of the competition during the finals series in order to make it to the big dance.
The Hawks u15s dismissed the strong Scarborough line-up for just 145 runs in the first innings of the season decider.
Demi Bullock made best figures of 3-20, with wickets also taken by Mitch Reader (3-22) and Cameron Hall (2-19).
The Hawks boys powered to victory, losing just three wickets with half-centurion Joel Baverstock (55) named Player of the Match.
Baverstock's efforts were closely backed by team mate Claus Lotter who produced a classy unbeaten 50, to help the side to a seven-wicket victory over Scarborough.
The two premierships are a massive boost for the club which has worked hard in providing the best possible opportunities for its juniors.
It was a perfect send-off for Gosnells u17s head coach Bruce Bussanich who announced his retirement after many years of service to the club.
