Playing in Pool B, Thailand lost the first clash when the resurgent Jelena Dokic vanquished beat Suchanan Viratprasert 6-1 6-2 to give Australia the first point.
Later Smantha Stosur clawed back from 2-5 in the second set to upset Tamarine Tanasugarn 4-6 7-5 6-0 and helped her team to top the group with two wins including the 3-0 victory over South Korea on Wednesday.
Thailand which beat Taiwan 3-0 is now 1-1 and is unlikely to win the pool which should be dominated by the powerful Australia.
