"It has been an extremely satisfying year personally and for the fantastic team around me, and I am thrilled to receive the Greg Norman Medal," Lee said.
"Winning another major was obviously a highlight this year, but watching Grace win her first at Evian was certainly another moment to remember.
"I have no doubt she will be nominated for plenty more awards like this one for years to come."
Lee and Kim's victories marked the first time two Australians had won majors in the same year since 2006, when Karrie Webb and Geoff Ogilvy triumphed.
Last month, Lee and Kim teamed up with Hannah Green and Steph Kyriacou to win the biennial International Crown for Australia in South Korea.
