Top Illawarra bowlers Dawn Hayman and twins Natalie and Samantha Noronha won gold and helped NSW sweep the major titles at the Australian under-18s bowls championships in Sorrento, Western Australia.
The Blues claimed the overall title at the four-day championships featuring 80 of the best juniors from across the country.
NSW finished with three gold, two silver and three bronze medals from just eight disciplines, as well as winning the boys, girls and overall state champions trophies.
NSW clinched the overall title from Victoria 72 points to 68 after a thrilling 14-11 win in the boys fours final.
Fairy Meadow's Dawn Hayman combined with NSW partner Jamie-Lee Worsnop to triumph 15-13 over Victoria in the girls pairs gold medal decider.
After the championships, Hayman and Worsnop both retained their spot in the Australian under-18s squad.
"It's great to make the Aussie squad for a third straight year," 16-year-old Hayman said.
"And to win the pairs at the Aussie title with Jamie, my best friend, was awesome. That's the biggest win I've had and to also win the national title was really special."
The Noronha twins and Ellen Ryan won the gold in the girls triples, beating South Australia 18-15 in the final.
Hayman and Worsnop joined the Noronhas in making the gold medal match in the girls fours, losing to the Victorian side 15-10.
Former Figtree RSL player Dylan Skinner won bronze in the boys singles, and Braiden Leese of Queensland took out the gold.
Skinner also won silver in the boys pairs.
With the Noronha twins to enter the senior ranks in 2014, Hayman is now the only Illawarra-based junior in the Australian under-18s squad.
Australia will take on New Zealand in seniors and juniors in their annual trans-Tasman series in Traralgon, Victoria, next March.
Meanwhile, Hayman is hoping to again qualify, next month, for next year's Australian Open, the nation's biggest tournament.
She reached the quarter-finals of the Open this year as a 15-year-old, bowing out to Shell Cove-based Karen Murphy.
