Former Irish international Trent Johnston has been released by New South Wales after three years in charge.

Johnston won two one-day trophies with the Australian state, but paid the price for his side's disappointing form in the first-class Sheffield Shield.

"It's been a great experience to work with the playing group and I wish them all the best in the future," Johnston said in a statement issued by Cricket NSW.

"I'd also like to thank the coaching and support staff for their support throughout the last three years.

"To everyone at Cricket NSW thank you, especially the board and chief executive Andrew Jones for the opportunity to coach NSW. I wish Cricket NSW every success."

NSW Cricket Performance Manager David Moore added in a statement: "As a former Blues player Trent understands the high expectations on all players and staff in NSW cricket."
