In recent years Blewett has combined commentary with his playing commitments, but he admits that he reached his retirement decision in light of the events that took place in his career in the last one year.
Incidentally, the former Australian all-rounder last year infamously branded selectors as ''clowns'' for not choosing him in the squad.
''I still feel like I could play for another couple of years physically, but in light of the events that have happened in the last 12 months or so, it (retirement) was the right decision,'' Blewett was quoted by The Daily Telegraph as saying.
Blewett, who made 15 Test half-centuries, said his inability to compile large scores for Australia was the biggest regret of his life.
''I probably underachieved a little bit for Australia. Something that really frustrated me throughout my career was that I got a lot of 50s, and you look at all the good players ... when they get to 50, they get 100.
''That probably ended my career playing for Australia, I just didn't convert those scores into big 100s,'' he said.
The 35-year-old flamboyant all-rounder played 46 Tests for Australia between 1995 and 2000, scoring 2,552 runs at an average of 34, apart from picking up 14 wickets with his medium pace bowling.
