The Australian Open has been given a huge boost after world No.2 Jordan Spieth committed to the event for a third straight year.

With the tournament at Royal Sydney Golf Club from November 17-20 leading into the World Cup of Golf in Melbourne, officials are expecting a bumper field.

And Spieth, who won the Australian Open in 2014 before finishing tied second with Adam Scott behind Matt Jones last year, is the first big name to confirm his entry.

"I have really enjoyed my previous visits to Australia and I can't wait to get back in November," Spieth said.

"I look back at my win with great memories as it helped me build momentum for 2015."

Spieth's 2014 win at the Australian Open came with an eight-under par 63 on the final day, helping to springboard his career as he went on to win six events in the following year, including the Masters and U.S. Open.

"Jordan is one of the greatest players in today's game and has proven to be exceptionally popular with audiences in Australia and around the globe," said Golf Australia CEO Stephen Pitt.

Pitt also confirmed that the 2017, 2019 and 2021 Australian Opens would also be played at Royal Sydney, with venues for the other years yet to be finalised.
