About Us

Mike and Mia Thew have more than 50 years combined experience in Australia and overseas in wide-ranging facets of the thoroughbred industry – particularly breeding, yearling preparation, and marketing.


Their composite skills and knowledge bring to Crowningstone a management balance that can be matched by very few breeding operations of this size.

About Mia


Mia began her career in the thoroughbred industry in a hands-on role at racing stables, as a stable hand and track rider before successfully completing an Associate Diploma in Agriculture – Equine Studies at Roseworthy Agricultural College.

Mia then worked at prominent thoroughbred nurseries in New Zealand and Australia, enabling her to gain a wealth of experience and knowledge in breeding practices, mare management, foaling, weaning, handling, yearling preparation, racehorse education and pre-training.

Later, working as a Pedigree and Bloodstock Supervisor for Gold Coast based Magic Millions, Mia gained a sound insight into effective marketing strategies and the requirements and standards for sale-quality horses.

Horse health, conformation, foal care, nutrition and yearling sale preparation are Mia’s areas of specialisation.

Mia an EFA level 1 instructor is an accomplished rider and enjoys instructing and judging when time is available. She continues to be very active in the education of staff for thoroughbred and related industries.

About Mike


Considerable international experience including three years at revered North American stud Spendthrift Farm as well as management roles including a six-year stint at Wakefield in the NSW Upper Hunter has enabled Mike to garner a wealth of knowledge and experience.

In the latter role, Mike was one of the first managers in the Hunter Valley to adopt and promote the practice of walking in mares to visit stallions.

He holds a Diploma of Applied Science – Agriculture from Wagga Wagga Agricultural College (now Charles Sturt University) and a Graduate Certificate in Financial Management also from CSU.

At Spendthrift in Kentucky, Mike managed client broodmares, and this instilled in him the importance of quality husbandry and management of breeding stock and the enormous potential the international breeding industry has and the part Australia can play in the realisation of that potential.

Mike also has a decade of experience in tertiary training for the horse industry being employed by Scone Equine Studies Centre as head teacher (1995 – 2006), training staff for the horse industry and maintaining close links with the breeding and racing industries.

Mike’s expertise in the areas of breeding, mating planning and pasture management balance the varied skills Mia brings to the Crowningstone team.
