The Australian tennis team will play its crucial Davis Cup World Group playoff against Switzerland on the grass courts of the Royal Sydney Golf Club.
Next month's match will be the first time a major tennis event has been held at the venue in Sydney's eastern suburbs for 10 years.
The winner will advance to the top-flight World Group next year.
Australia beat China 3-1 in the second round in April.
Switzerland, with Roger Federer playing doubles and singles, defeated Portugal 5-0.
