The 30-strong Australasian contingent blends experience with newcomers to the professional game as they look to gain access to the Asian Tour which begins with next week's SMBC Singapore Open.
The 90-hole Final Stage will feature 240 players with the field cut to the leading 70 and ties through 72 holes ahead of the fifth and final round held at Rayong Green Valley.
At the conclusion of 90 holes, the top 35 players and ties will be ranked accordingly for the 2018 season.
Recent Australasian Tour winners Jarryd Felton, Cory Crawford, Ashley Hall and Travis Smyth are in the field and so too are veterans Gareth Paddison, Michael Wright, Darren Beck, David Gleeson and Steven Jeffress.
Cory Crawford won last year's PNG Open in a six-hole playoff.
Former Australian Amateur Champions Andrew Martin, Matt Stieger and Gleeson will look to get their careers heading in the right direction with so much at stake for the wide mix of Australasians seeking a place to ply their trade this year.
Another noteworthy Australian teeing it up is Asian Tour winner Kieran Pratt who will seek to reignite his golf career after almost two years away from the professional game.
Pratt - who won the 2012 Myanmar Open - has not competed in the pro ranks since a T15 finish at the 2016 Victorian Open.
