INAS claimed the former World Boxing Organization welterweight champion, who calls the host city his home, was a natural choice to spread the word about the event.

"I’m honoured to join the INAS Global Games and am very excited to play a role in this inspirational celebration of athletic ability," Horn said.

The INAS Global Games, held every four years, is the world’s largest high-performance sports event for athletes with an intellectual impairment and will this year be held between October 12 and 19.

More than 1,000 athletes will compete across nine sports in a "celebration of sport, culture and ability".

"Being born and bred in Brisbane I am very proud to be an ambassador for this major sporting event and I am certainly encouraging everyone to come along and experience the unique greatness of these Games," Horn said.

"With athletes from up to 80 countries proudly contesting success throughout these Games, we will see not only exceptional athletic prowess, but witness the courage and determination as these international athletes strive to be the very best that they can be."

Horn joins Australia’s tennis legend Pat Rafter and Paralympic swimming sensation Daniel Fox as ambassadors of the Games.

"It’s great to have Jeff along on the Global Games 2019 journey with the compelling passion and sheer determination he shows in the ring," said Robyn Smith, chief executive of the Global Games Sports Company.

"I know his reputation and ability to connect with all of Australia and globally he will be a real benefit in promoting the INAS Global Games.

"It is not only Jeff’s fighting spirit and his success in the ring that makes him the perfect ambassador, it is his humble demeanour and personal commitment for inclusivity in schools and society, as he leads the way to reduce bullying and discrimination, that makes him stand out."

In joining Rafter and Fox, Horn will be actively promoting the vision of the Games – that inclusive sport has the ability to change attitudes, challenge perceptions and strengthen communities both locally and globally.

Australia are expected to be strong performers at the Games having finished top of the medal table at every edition since 2009.

The event will be held less than a year before the Tokyo 2020 Paralympic Games.
