Dr Michael Powderly - Chiropractor
Coalfields Spine Care, Moranbah QLD
With over 35 years of experience and continual learning, I’ve been privileged to help thousands of people—from all walks of life—recover from injury, overcome ill health, and experience profound healing, often in cases where the situation seemed complex or even hopeless. Chiropractic, when practiced with precision and insight, truly unleashes the body’s incredible ability to heal itself—and I’ve seen that power in action time and time again.
I began my career in Bunbury, Western Australia, back in 1990, mentored by a local legend who instilled in me a deep commitment to clinical excellence—especially in mastering the fundamentals: disc injuries, neck and low back pain, headaches, and more. Over time, I extended that foundation to working successfully with more complex cases, including autoimmune conditions, chronic pain, and long-standing injuries.
Throughout my career, I’ve worked across Victoria, New South Wales, and WA—running my own practices in Melbourne, Murwillumbah, and Byron Bay, and, for the past 15 years, serving as an associate and locum Chiropractor in both metro and regional areas.
My approach is vitalistic: the Power that made the body, heals the body. My job is to ensure your body has everything it needs to do the job of healing itself—fully and efficiently.
My clinical background is diverse. I’ve worked with everyday Australians—miners, loggers, tradespeople—as well as elite athletes, including Olympic swimmers and kayakers, AFL and Super Rugby players. I’ve been called on by international touring artists, and even once by a visiting Guru with over 90 million followers. Whoever I’m treating, my commitment is the same: to deliver clear explanations, real solutions, and lasting results.
Over the years, I’ve trained in many technique systems—Applied Kinesiology, SOT, NOT, NET, Sports Chiropractic, and more—but what matters most is keeping it simple, effective, and tailored to you. I take pride in helping people connect the dots, understand what’s going on, and feel confident in their recovery.
Outside the clinic, I’m an avid adventurer and lover of the outdoors. Whether it’s surfing, mountain biking, hiking, snowboarding, scuba diving I find joy in staying active—especially with my partner Catherine and our three grown boys. I also give back where I can: I’ve spent many years as Captain of the St Kilda Lifesaving Club and continue to volunteer as a Life Saver and Sports Chiropractor for charity football events in Melbourne.
If you’re ready to feel better, move better, and live better—I’d love to help.
