The NSW National Coursing Association Ltd was formed by the late Richard Coombes and his late brother Frank Coombes.

The NSW NCA's major racing base was the famous Rooty Hill track where many of the countries finest greyhounds competed in the "coursing" events before the mechanical lure became the major form of racing.

The Orange Racecourse enclosure was the first to host the NSW Waterloo Cup under the NSW NCA banner, arguably the most famous of all coursing events in Australia. Winners of the Waterloo Cup include the legendary Terminus in 1926 and again in 1927, Andy in 1929, Andy's Choice (a son of Andy) in 1931 and Tecoma Dan in 1935.

When the NCA's major complex Wentworth Park was enjoying its glory days in the 1950's, 60's, and 70's, crowds would often reach the 25,000 mark with yearly averages of more than 16,000 patrons per meeting.

In 1975, the NSW NCA finalised nine years of negotiations when it signed a 50 year lease for the use of the Wentworth Park complex. In 1987, the other major greyhound body in New South Wales, the Greyhound Breeders, Owners and Trainers, relocated its main racing base from Harold Park to enter into a shared arrangement with the NCA at Wentworth Park.

Now, the two bodies race shared dates that sees greyhound racing take place at Wentworth Park every Monday and Saturday night of the year.

The NSW National Coursing Association has many features events with the flagship being the Group 1 Paws of Thunder. Others include the National Derby, National Futurity, Sydney Cup, Young Star Classic and Potential Stakes.

The NSW NCA also hosts the NSW Greyhound of the Year and some of the countries greatest greyhounds in the past 35 years appear on the honour roll.

In September 2005 the National Coursing Association officially opened The Gardens Greyhound & Sporting Complex, located at Birmingham Gardens on the outskirts of Newcastle.

Recognised as one of the leading greyhound facilities in the world The Gardens has been an instant success constantly hosting large crowds in its many facilities and receiving excess nominations for all race meetings.
