Stefan Milicevic, 29, fixed six matches - including five in which he played - and attempted to fix a further six between 2022 and 2024, the International Tennis Integrity Agency (ITIA) said.
"Milicevic was also charged with recruiting or attempting to recruit multiple professional players as part of a corrupt network during the same period, resulting in a number of other players fixing matches," the ITIA said in a statement.
Milicevic, whose highest ATP ranking was a lowly 1,338, did not engage or co-operate with the investigation, according to the ITIA, and was also fined $70,000 (£52,604).
The ITIA added: "While suspended, Milicevic is not allowed to play in, coach at, or attend any events organised or sanctioned by World Tennis, WTA, ATP, the Grand Slams, or any national association."
His suspension will officially end on October 8th, 2050.
