Dr Craig Challen SC, OAM

2019 Joint Australian of the Year, Thai Cave rescuer

Dr Challen is regarded as one of the best technical divers in the world. It was due to his prominent reputation that Craig and his dive buddy Dr Richard Harris were called upon to assist in the rescue of a young football team and their coach from the Tham Luang Cave in Thailand in a case that had the whole world on tenterhooks. In a delicate two-week operation it took extraordinary courage, determination and technical skills to successfully complete the harrowing rescue of the 12 boys and their coach from a mile and a half underground and underwater. 
Craig shares how he and Richard Harris came together with one common goal in mind and how teamwork, leadership and determination won the day.  Craig will include some amazing vision in his presentation and inside information on the rescue, which is not generally common knowledge.

Convention Breakfast – Justin Langer AM

Until the announcement of his retirement from test cricket in 2007 Justin was one of Australia’s great top order batsmen. Originally playing at number three, he moved to opener in 2001 and played 105 test matches scoring 7,696 runs including 23 test centuries. Few have worn the baggy green with greater pride.

In July 2009 whilst playing country cricket in the UK, Justin surpassed Sir Donald Bradman as the most prolific batsman in Australian cricket with a total of 28,068 first class runs. After retiring from his playing career Justin started his coaching career. In November 2009, he was appointed Batting-Mentoring coach of the Australian test cricket team and in May 2011 was appointed Assistant Coach. In November 2012, Justin achieved a long-held dream when he was appointed Coach of Western Australian cricket (Western Warriors and Perth Scorchers).


After six very successful years as Coach of Western Australia Justin was offered the highest position in Australian cricket in May 2018 when he was appointed Coach of the Australian cricket team. After four years in that all-encompassing role, Justin resigned to spend more time with his family and friends. Leading into his decision, the Australian men’s Test cricket team had won the T20 World Cup for the first time, the Ashes and were ranked the number one team in international cricket. At the same time, Justin was entered in the Australian Cricket Hall of Fame and was awarded Wisden’s Coach of the Year.

Justin is patron of Solaris Care, Children’s Leukaemia & Cancer Research Foundation, Kyle Andrews Foundation and an ambassador for The Fathering Project, the Ear Science Institute Australia, the Bravery Trust and Ovarian Cancer Australia. He was named as a Member of the Order of Australia (AM) for his services to Australian cricket and the community in 2008 Queen’s Birthday Honours List.
