LIV Golf on Sunday extended its agreement with Adelaide until 2031, with new chief executive Scott O'Neil calling the Australian tournament "the embodiment" of everything the Saudi-backed league represents.
Adelaide's Grange Golf Course is currently hosting its third edition of LIV, with more than 100 000 fans expected through the gates over the three days.
"This event is the embodiment of what LIV Golf represents: the biggest stars, the best courses, unmatched experiences, and of course, the best fans in the world," said O'Neil.
"LIV Golf Adelaide is our showcase and brings the vision for all our events across the globe to life."
Adelaide has been named World's Best Golf Event at the World Golf Awards for the past two years.
As part of a new agreement with the South Australia state government, the downtown North Adelaide Golf Course will be redeveloped so it can host LIV tournaments.
The design will be led by Australia's Greg Norman, who was instrumental in establishing LIV Golf but was replaced by O'Neil last month.
"I've dreamed of building a global golf league for 30 years," said Norman, a polarising figure in the rift between the established PGA Tour and LIV Golf, which is owned by the Saudi Public Investment Fund.
"LIV Golf Adelaide is the realisation of what LIV Golf can be around the world.
"I'm honoured to design a world-class course that will benefit current and future generations here in Australia," he added.
The LIV Tour's 14-stop 2025 campaign teed off last week in Riyadh and moves to Hong Kong after Adelaide.
