Golf Australia chief executive James Sutherland said last year's tournaments, also with an equal split between men and women for prize money, had a "resoundingly positive impact".
"Last year the world-first national open format pushed boundaries and broke new ground for golf," he added, with the biggest crowds in a decade.
"The event will be further enhanced this year and will again talk to our commitment to growing golf as a sport for all."
Sutherland has previously said that he wanted golf to have a more "inclusive look and feel" and that commercial partners "absolutely love this concept".
In Melbourne last year Poland's Adrian Meronk won the men's Australian Open, co-sanctioned by the DP World Tour, while South Africa's British Open champion Ashleigh Buhai took the women's title.
This year's tournaments will be hosted in Sydney on November 30-December 3 at the Jack Nicklaus-designed Australian Golf Club across the four days. The nearby Lakes Golf Club is co-hosting for the first two days.
