Federation of International Polo interim president James Ashton died on Sunday following a fall during a 10 goal match in Thailand.
Mr Ashton, 69, is to be buried on February 26 on his family's polo field at Millamolong Station.
Media reports indicated Mr Ashton's horse fell while galloping. He died on the way to hospital in Pattaya.
Mr Aston, a former president of the Australian Polo Council, took on the role at FIP in December, following the resignation of three major polo nations from the federation. He was visiting Thailand in his role as FIP President.
As well as playing and organising polo throughout the world in past years, James Ashton was integral to the organisation of the 2001 World Cup Polo Tournament in Melbourne.
The Ashton name has historic ties with polo in Australia, dating back to about the 1920s, and James Ashton led a polo pony breeding programme at his family's Millamolong Station. Many of the current bloodlines descend from the original Ashton polo ponies who travelled to England in 1930. In recent years Mr Ashton was the first in the Southern Hemisphere to breed a sex sorted foal for polo.
A private funeral is being held on February 26 at 10.30am, followed by a public burial at the Millamolong Polo Field, about four hours out of Sydney in New South Wales.
Mr Ashton is surviced by his wife, Susan.
