Two-time Paralympian high jumper Aaron Chatman, who won two Paralympic medals in the discipline, has announced his retirement at the age of 33.
Chatman leaves behind a long career after he first achieved success at the age of 19 when he won the silver medal at the 2006 International Paralympic Committee (IPC) Athletics World Championships in Assen in The Netherlands.
The following year, he broke the world record in the T47 class with a height of 2.05 metres at the 2007 Australian Capital Territory Championships in his home of Australia.
On his Paralympic debut at the Beijing 2008 Games, he won silver with a clearance of 2.02m and followed it up with a bronze medal in the 4x100 metres T42-46 relay at the same event.
Following a hiatus, he won bronze in the high jump at the Rio 2016 Paralympics, before winning silver at the World Para Athletics Championships in London the following year.
Due to complications from chronic injuries, Chatman decided to call time on his career.
"Competing in athletics has brought me so much over the years," said Chatman.
"I've learned so many things about myself as a person and what I am capable of, and also not to take things for granted as life can change in an instant.

"With less than a year to go until Tokyo, I have decided to step down mainly due to an ongoing ankle injury that has not recovered 100 per cent.
"I feel that I would no longer be able to reach the performance level I have been at for previous Games and international competition."
Chatman was praised by Athletics Australia general manager of high performance Andrew Faichney, who thanked him for his contribution to the sport.
"Our sole high jumper on the Para-athletics team for quite some time now, Aaron has been an integral part of our High Performance Para Programme," said Faichney.
"He's led by example on and off the field with his positive attitude and his determination, which has ultimately led him to earn selection on multiple Australian teams."
During his early career, he was coached by Iryna Dvorskina who has been integral to Australia's Para-athletics success for over a decade.
Chatman was classified T47 as an amputee below the elbow on his right arm.
