The American will lead Garmin-Sharp's attack around Adelaide between January 21 and 27 having fully recovered from a severe concussion suffered in September that ruled him out of the rest of last season.
Farrar will be supported at 2013's first World Tour race by Australians Lachlan Morton, Steele von Hoff, Nathan Haas and Rohan Dennis, as well as Jack Bauer of New Zealand and South African Robert Hunter.
The 28-year-old sprinter managed just two wins last season - a pair of stages at the USA Pro Cycling Challenge - while he finished second overall at the Tour of Qatar and the Scheldeprijs.
Farrar returns to the race in Adelaide for the first time since 2011, having skipped last year's event.
