With Cork struggling financially Gamble was allowed to look for a new club and joined Hartlepool United for a trial in December 2009.

Gamble made 13 league appearances in midfield for the Shannonsiders as they narrowly missed out on a promotion play-off place to Monaghan United.

[6][7] Following the completion of the trial Brunei DPMM announced they would be signing Gamble along with Robert Alviž and Boris Raspudić.

He manned the substitutes bench in a match against Chile, but a poor performance saw Staunton unwilling to experiment late in the game.

In May 2007, it was announced that Gamble had again been drafted into Steve Staunton's Republic of Ireland squad to travel to the United States to take part in friendly matches against Ecuador and Bolivia.

Retiring at the end of 2015, he then worked as a fitness coach at Waterford FC in 2017 and later in a similar role at his former club, Limerick, from 2018 to 2019.
