Australia's Premier Equestrian Event
18 to 21 November 2021

What is the Aus3de?

The Equestrian 3 Day Event – commonly known as ‘Eventing’ – is the triathlon of Horse Sport comprising the three phases of Dressage, Cross Country and Jumping over 3 days on the same horse.

Held annually on the third weekend in November, the Australian International 3 Day Event (Aus3de) is Australia’s premier equestrian competition.

It is the only CCI five star event held in Australia, the only one held in the Southern Hemisphere and one of only seven held across the world. For the past twenty two years, Adelaide has been the chosen host city of this Hallmark Equestrian event.

The 2021 Adelaide event will also have the biggest prize pool in the Southern Hemisphere with over $150,000 up for grabs!

The Aus3de proudly takes its place alongside the other great international five star events: the Kentucky Three Day Event in the United States in April; Badminton Horse Trials in England in May; Luhmuhlen Horse Trials in Germany in June; Burghley Horse Trials back in the UK in September; Maryland at Fair Hill in the US in October ; and Pau Horse Trials in France also in October.

The Adelaide event however is unique in the world, being the only one staged in the heart of a vibrant city centre, taking place in Adelaide’s  picturesque  East  Parklands.

The Adelaide International Horse Trials was born in 1997 to replace the Gawler Horse Trials that had been staged at Gawler, north of Adelaide, since 1954.

The new event debuted in Adelaide’s East Parklands with a Three Star rating but was subsequently upgraded to a Four Star (now Five Star) rating in 2002 to become the only event of this calibre in the Southern Hemisphere.

The competition was relaunched and renamed the Australian International 3 Day Event (Aus3de) in 2007 to celebrate the event’s tenth anniversary and better reflect the international focus of the competition.

In 2019, the Aus3de was upgrade to five star status, along with the other 5 international greats, in line with the updated FEI category designations.

The Aus3de is owned, managed and marketed by the Not for Profit Board of Adelaide Horse Trials Management Inc comprising equestrian greats, professional business directors and media advisers.
