The US Open is played on Laykold while the Australian Open is played on GreenSet, both acrylic-topped hard court surfaces. Historically for the Grand Slams hard courts have been used at the US Open since 1978 and the Australian Open since 1988.
The six group winners, plus the best runner-up from both Sydney and Perth, will qualify for the knockout stage creating an eight-team bracket. If Australia finishes first in group C it will head to Sydney and face the winner of group F - Croatia, Netherlands or Norway - on January 4.
