A persistent back complaint that curtailed his cricket over the past 12 months and saw him miss out on a playing contract with the Queensland Bulls this season saw him reconsider his playing future.
After a period of reflection, he confirmed today he would bring down the curtain on his career.
Through his Alister McDermott Cricket Academy website, 'Ali' outlined what had motivated him during his playing days and how he had dealt with adversity across his career.
"From a young age I gave my full commitment to fulfilling my dream, looking to improve my fitness, strength, and skill level,'' he wrote.
"Even though I did not have the extended career I had dreamed of as a kid due to injuries, form and self-confidence, I have had some amazing memories that I can be proud of, and was fortunate to play with some absolute legends of the game."
McDermott, 29, will continue as Wynnum-Manly club coach in the Bulls Masters Premier Cricket competition and said he was enjoying coaching immensely.
"Nothing beats being able to help and watch the development of a player, learning new skills, and see their pure enjoyment in playing the game. This is what drives me to be a better coach every day,'' he noted.
"I recently finished a 3-day holiday camp, and after what has been a challenging several months for everyone, to see nearly 50 kids constantly running around with beaming smiles on their faces, playing cricket, was a great feeling to have again."
McDermott made his debut for Queensland as a 17-year-old in the old KFC Big Bash T20 competition and went onto play 20 first class games and 27 one day matches. He was a BBL player for the Brisbane Heat and Sydney Thunder teams.
He won one-day (2012-13) and Sheffield Shield (2011-12) titles with Queensland and was a member of the Heat's BBL|02 championship team, taking 2-21 including the key scalp of Mike Hussey in the Final win over the Perth Scorchers in Perth.
A clever swing bowler, he took 69 first class wickets at 25.92 for the Bulls, with a best haul of 7-24 in an innings. In one-day cricket, his best return was 5-64 for Queensland as part of 40 wickets at 27.50.
Among his career high points were Australia 'A' selection in first class and one day cricket, and touring the United Arab Emirates as part of the Australian squad for T20 and ODI games against Pakistan in 2012.
After a three-year absence, he was contracted by Queensland for the 2019-20 season but a spate of injuries, including a broken wrist in a off-season fielding accident, prevented him playing any games for the Bulls and he was left off the list for this summer as he fought to recover sufficiently to bowl again
