Dr Harris, an Adelaide anaesthetist, and his mate and retired vet Mr Challen captured worldwide attention for their part in the daring rescue mission which saved a team of 12 young Thai soccer players and their coach from a flooded cave.
Dr Harris wants to use the platform to encourage children to get away from screens and be adventurous outdoors.
"I do fear for kids today who, living in a risk averse society, will not learn to challenge themselves and to earn the grazed knees and stubbed toes that really are necessary to build resilience and confidence," Dr Harris said.
Mr Challen said the rescue was a metaphor for taking opportunities in life.
