Thrive Nutrition & Dietitics was founded by Amanda Watts (nee Cossey)- an Accredited Practicing Dietitian, Accredited Nutritionist and SDA Sports Dietitian. She is Australia’s most experienced climbing dietitian. Amanda is passionate about people feeling and performing the best they can. She takes an in-depth, evidence based approach to nutrition, health and performance. Amanda founded Thrive N&D to help people and athletes of all levels achieve their sporting dreams and health goals and to help non athletes evolve into a healthier and happier version of themselves.

Amanda grew up as an athlete, transitioning from junior gymnastics, into state level Little Athletics and A grade netball. Then she found rock climbing. Amanda moved to the Blue Mountains from Western Australia in 1999, to live and climb in one of Australia’s greatest rock climbing areas. When not working as a dietitian, Amanda is climbing around her home in the Blue Mountains, training or travelling around the world to climb in new places. Amanda has been climbing for 22 years, has represented Australia in World Cup sport climbing, has consistently been on the podium at bouldering nationals and has performed at an elite level across several outdoor disciplines including sport and trad climbing.

She is a brand ambassador for Black Diamond, Sea to Summit and Evolv.

Amanda is also a regular columnist for Australia’s digital climbing magazine, Vertical Life.
