Japan's Hiroshi Iwata and Yoshinobu Tsukada, Chinese Taipei amateur Pan Cheng-tsung and China's Ashun Wu each earned the right to play the Open Championship in July at Royal Liverpool.
Tsukada won his place with a birdie at the 4th extra hole of a playoff against three other golfers.
The leading Australian was European Tour player, Wade Ormsby who finished one shot out of the playoff while Aaron Townsend finished a further shot back.
Iwata, who led the qualifiers at Amata Springs near Bangkok, last week played the New Zealand Open where he finished midfield as did Townsend.
