Smith has now been shuffled back to 11th in the world as a result of not receiving world ranking points following his move to LIV Golf.
The 2022 Open champion has three more tournaments left on the LIV Golf League this season before he heads home to Australia.
Smith has won twice this season with victories in London and Bedminster.
He played in all four majors and chalked up two top-10 finishes at the US PGA (T9) and the US Open (4).
Smith also finished T34 at The Masters and T33 at The Open.
The Australian will bid to defend his Australian PGA Championship title at Royal Queensland in Brisbane from November 23 to 26.
He has won the event three times before with victories in 2017, 2018 and 2022.
The last player to win the Australian PGA four times was Robert Allenby in 2009.
Smith will then go in search of winning his first Australian Open title the following week at The Lakes in Sydney from November 30 to December 3.
"I'm coming back home to play some golf," said Smith.
"I loved coming back down to Australia just to hang out, but to play golf in front of the fans is something that I love doing and I'm happy that I'm coming back home.
"I've been fortunate to have a few PGAs, haven't quite got the Open yet so that's something that I want and I'll be working hard to get it done."
PGA of Australia CEO Gavin Kirkman said: "Cam will be trying to join an elite group of golfers by winning the Kirkwood Cup (Australian PGA) for a fourth time this November and I'm sure he'll be ready to put on a great show once again at Royal Queensland.
"Cam continues to support his home tour each year and the fans just want to see him live and in action showcasing his game while inspiring our next generation of players girls and boys to reach their peak.
"With Cam locked in for both fields, the Australian PGA and Australian Open will be must-see events."
