Hyundai A-League - Fowler leaves Perth Glory
Fowler spent a year at the Western Australia club, scoring nine goals in 28 A-League appearances.
He had spent the previous season at North Queensland Fury, for whom he also netted nine league goals, but has now decided to return to England to be closer to his family and concentrate on forging a career in coaching.
"Firstly, I'd like to show my appreciation to the chairman for his understanding," said Fowler, 36.
"The chairman has been exceptional since I signed for the club, and I thank him for the opportunity to play for Perth Glory.
"I have a wonderful and loving family to consider and with the children in school, it's best to keep them settled.
"I also need to stay in the UK to complete my coaching badges.
"I thank everyone at Perth Glory and in Western Australia for making me feel so welcome and I wish (manager) Ian Ferguson and the players all the best for the coming season."
Glory chairman Tony Sage supported Fowler's decision.
"Robbie has put Perth Glory on the world map and while I would've loved to have him here for a second season, as a husband and father I understand that his family comes first," he said.
"I also appreciate the fact that Robbie called me personally to tell me of his decision.
"Robbie will always be welcomed into the Perth Glory family and I can't thank him enough for his contribution to the football club."
