Great Britain will compete in January’s inaugural ATP Cup following Andy Murray’s late decision to enter for the competition.
Britain may not have qualified for the 24 team event had Murray not entered under his protected world ranking of two.
Novak Djokovic, Rafael Nadal and Roger Federer are also in for the new tournament, which will be played across three Australian cities.
The draw would takes place at the Sydney Opera House on Monday.
Hong Kong Tennis Open, slated for 5th October, has been postponed due to ongoing protests.
The organisers said they would be better placed to have a smooth running tournament at later time.
Hong Kong as been rocked by increasingly violent protests, triggered by an extradition bill for months now.
The bill has now been withdrawn but protests have continued and have grown to reflect wider demands for democratic reform.
The Hong Kong Tennis Open was originally due to take place between 5 to 13 October.
