Coolmore Australia chairman Ken Barry, who was heavily involved in pioneering the shuttle stallion concept in Australia, has died.

A lawyer, Barry was involved in the racing and breeding industry for more than 40 years, the past 25 as Coolmore Australia's chairman.

Coolmore paid tribute to Barry's contribution to the Australian breeding industry and his lasting influence on those who knew him.

"We at Coolmore can never repay the huge debt of gratitude we owe Ken for his work and wisdom, his advice and friendship to us all," Coolmore Australia said in a statement.

Barry's relationship with Coolmore began after an introduction to its proprietor John Magnier led to him becoming responsible for the international conglomerate's Australian legal interests.

His work included establishing a joint venture with Arrowfield Stud to pave the way for northern hemisphere stallions to travel to Australia for the southern hemisphere breeding season.

The introduction of shuttle stallions has been a game changer and the international bloodlines have produced some of the country's best sires including Redoute's Choice and Snitzel.

A part-owner of Encosta De Lago and Fastnet Rock, Barry was also a great mentor to many and was instrumental in fighting the introduction of the Drayton South mine in the Hunter Valley.
