Australia gave themselves a chance of regaining a place in the Davis Cup World Group when they routed South Korea 5-0 in their Asia/Oceania Group I second-round tie on Sunday.
World No.36 Bernard Tomic and Marinko Matosevic completed the clean sweep over the Koreans when they won their reverse singles matches at the Queensland Tennis Centre.
Tomic brushed aside Davis Cup debutant Na Jung-Woong 6-2, 6-1 in less than an hour after Matosevic had outlasted Cho Min-Hyeok 6-2, 2-6, 6-0.
The World Group playoff draw will be held next week, when Australia will find out if they are drawn against Canada, Italy, Switzerland, Germany, Russia, Sweden, Japan or Kazakhstan.
"Hopefully we draw the right team, and not Switzerland over there on clay," Tomic said.
