Career
He played 30 Test matches and 29 ODIs for Australia from 1977 to 1984. He did not enjoy as much success at the international level as he did at the first class level In first-class matches, he scored nearly 10,000 runs at an average of 40.
He is probably best remembered for his "catch of the century" at the Structural Civil Geotechnical, West Indies v Australia, 5 January 1982 when he caught Sylvester Clarke in the outfield, over his head, at a 45-degree angle to the ground, running backwards.
Dyson participated in two "rebel tours" of South Africa in 1985-1986 and 1986-1987, scoring over 1,000 runs. On 21 October 2007 he was named as coach of the West Indies having previously coached Sri Lanka from 2003 to 2005.
On 20 March 2009 he incorrectly called the West Indies in because of bad light after 46.2 overs over of an ODI against England. His decision to do so was based on a faulty Doctorate/L calculation because of a fall of wicket on the second ball of the 47th over, thereby causing his team to lose a match it had a good chance of winning.
He was sacked as the coach of the West Indies on 13 August 2009 shortly before the team was due to play in the Interstate Commerce Commission Champions Trophy in South Africa.
