Josh Younger led the charge as more than half the Australasians who teed up advanced from the first stage of Asian Tour Qualifying School last week.
Younger was one of 33 golfers from Australia and New Zealand playing across four courses in Thailand, the 33-year-old posting a one shot victory at the St Andrews 2000 layout.
The Victorian, who posted three top-10 finishes on the ISPS HANDA PGA Tour of Australasia in 2017, signed for scores of 64-68-70-70 to beat home fellow Australian Dale Brandt-Richards by a stroke.
They were among seven Australasians to advance from the biggest of the four fields competing with Ash Hall, Andrew Martin, Callan O’Reilly, Matt Stieger, Oliver Goss and New Zealand’s Gareth Paddison also making the grade.
At the Rayong Valley course three Australians were among the 43 qualifiers, Michael Choi, Mitchell Brown and Jacob Boyce finishing inside the 3-over score required.
Nathan Mann and Dale Williamson finished inside the top-12 to qualify from the 41-player field at the Silky Oak course while Cory Crawford, Michael Wright, Troy Moses and New Zealand’s Woonchul Na were among the 20 players to advance from the Windsor Park course.
The addition of the 17 players from the first stage will now see 30 Australasians tackle the final stage this week where 35 cards will be decided for the 2018 Tour.
The final stage is played over 90 holes with 242 golfers teeing up. There will be a cut after the first 36 holes with only the leading 140 players continuing and a second cut after 72 holes to the low 70 and ties.
The final stage will be played at the Rayong Valley and St Andrews 2000 courses.
