Stationed in the Netherlands since 2015, he travels to Australia, the United States and around Europe holding events to train drivers.

Along with competing in four-in-hand driving sports, Exell has been active in breaking, training, buying and selling horses.

[3][4] The nice thing about carriage driving is that we can host our sponsors and owners and we can take them to Royal Ascot on a coach (an English Park Drag) with a team of horses.

Bill was an Orlov Trotter born in 1992, previously driven by Michael Freund [de; fr] with whom he won five consecutive World Cup Finals, beginning with a 2002 victory in Sweden.

Exell started driving Bill in 2007, and won a bronze medal with him at the World Championships in the Netherlands in 2008.

"[15] Boyd Exell was awarded an Order of Australia in the 2014 Queen's Birthday Honours list for services to equestrian sports.

[11] In a 2021 presentation of his competition career, FEI said of Exell, "Behind Boyd's success lies his genuine love of horses and a deep sense of connection with his animals, and it's this mutual understanding between Exell and his horses that has made them a formidable partnership on the international carriage driving stage, and truly an equestrian icon".

At 16, Boyd started to compete seriously in driving competitions in Australia and won the Australian National Championships with a Hackney Pony pair.

As a backup to a career with horses, and due to pressure from his mother, he apprenticed with a local engineering firm.
