Groth's name was added to an honour role that includes three-time winner Sam Stosur, Lleyton Hewitt and Nick Kyrgios. 
With top-30 pair Kyrgios and Bernard Tomic both ruled ineligible for disciplinary reasons, given that there is now an "ambassadorial" element on top of the excellence requirement for the top gong at Tennis Australia's annual awards night, Groth was chosen ahead of fellow nominees Stosur, rising star Thanasi Kokkinakis, doubles specialists Casey Dellacqua and John Peers and wheelchair champion Dylan Alcott.
In 2011, Groth spent part of a season playing suburban football with Vermont Eagles in Melbourne's east as part of the healing process after injury and a marriage split, unsure of what his tennis future would hold. A hugely positive answer has come in the past 20 months, his ranking having been as low as 176th just last   March.
This year, which he started ranked 81st, the 193-centimetre Groth won Challenger titles in Taiwan and Manchester, reached the third round at Wimbledon and - with Hewitt - was a hero of Australia's Davis Cup quarter-final win in both singles and doubles against Kazakhstan in   July.
He peaked at No.53 in singles before his season was ended prematurely by surgery to repair a nerve problem in his right foot.
Once known solely for his thunderous serve, the affable Victorian has improved his fitness, groundstrokes and consistency under coach Ben Mathias, who was recognised as high performance coach of the year at the sixth annual presentation in Melbourne.
Ray Ruffels received the night's other major honour: the President's Spirit of Tennis Award, for his outstanding contribution to the sport as a player and veteran coach. Hewitt was also honoured and Omar Jasika and Kimberly Birrell were named the best junior athletes of 2015.
