[2] Brendan Nash qualified to play for Jamaica through his father, Paul, a Jamaican Olympic swimmer.

[5] On one occasion, Nash was pressed into service as a makeshift wicket-keeper for QAS when the first choice keeper was injured with a suspected broken thumb.

Nash made his debut for the Queensland Bulls in 2001 when he came into the side as cover for injured batsman Martin Love.

He achieved a cult following with a "Brendan Nash Fan Club" founded among university students in Brisbane.

[7] After not being given a contract with the Queensland Bulls for the 2007–08 season, Nash decided to try to restart his career by moving to the West Indies.

Speaking of his decision, he said "I was obviously very disappointed to miss out on a contract, but I pretty much got told it would be hard for me to work my way back in again and I felt I still have something to offer".

Though the semi-final against Trinidad and Tobago ended in a draw,[11] Jamaica faced Combined Campuses and Colleges in the final.

Nash was unable to bat for Jamaica due to injury, but the side went on to win the match by eight wickets.

[12] Having identified his limited-over batting as an area he wanted to improve on (he scored only 67 runs in five matches) he decided to play for Monton & Weaste CC in the Central Lancashire League (CLL) during the Caribbean's off-season (summer 2008 in England).

In 2012, Nash, having been dropped from the West Indies national side, signed for Kent, for the 2012 English county cricket season.

[17] On 5 November 2005, Nash fielded for Australia as a substitute in a Test match against the West Indies, for whom he would later play.

[18][19] On 12 August 2008 Nash was named in the West Indies One Day International (ODI) squad to play in the tri-series against Bermuda and Canada.

[4] He made his ODI debut on 20 August 2008 – along with batsman Leon Johnson and bowler Kemar Roach – when the West Indies played Bermuda.

In November 2009, less than a year after making his Test debut, Nash was awarded a central retainer contract with the West Indies Cricket Board (WICB).

The previous captain and vice, Chris Gayle and Dwayne Bravo, had chosen not to sign central contracts with the WICB and were replaced.

[43] After retiring, Nash moved back to Australia, and set up a mortgage broker firm in Brisbane.
