Welcome to OSO Arabians, our magnificent 4,000 acre stud farm, situated at the base of the Table Top Range, in the heart of picturesque, rural southern New South Wales, Australia.

'OSO’ Spanish word for Bear - revered by native Americans for their courage, strength & wisdom

Driven by a life-long passion for the Arabian horse, Linda Mars has long held a desire to see the bloodlines of Kelkette Park and Al Marah (USA) stay intact.


Over 25 years ago, inspired by the master-craft and breeding successes of Bazy Tankersley (Al Marah) and Margaret Bohm (Kelkette Park) - who both predominantly utilised the bloodlines of the Indraff/Raffles and Silver Moonlight/Silver family lines to produce their own version of a truly versatile Arabian, renown for its conformation, temperament, stamina and versatility - Linda decided to combine the unique bloodlines of Kelkette Park and Al Marah (USA) to create the very foundation blocks on which the OSO Arabians legacy is built.


Today, our unwavering commitment and primary objective remains unchanged; to further develop the diversity of the Arabian breed through our first-class breeding program, in order to evolve, expand and refine the capabilities and versatility of our horses.


More recently, whilst TEAM OSO's primary discipline remains the Endurance circuit - and we continue to enjoy increasing successes in both the domestic and international arenas - our focus on enhancing versatility and improving capability enables us to now compete extremely successfully in a broader range of disciplines.


Proudly, we are truly achieving our ultimate goal of diversity through versatility.
