Climbers from Australia

Inventor of the Ewbank grading system which is used in Australia, New Zealand and South Africa.

…the grading systems being used in other countries all had an inbuilt and totally unrealistic glass ceiling, which tradition made it impossible to change. Furthermore, they were all using subdivisions, which created false psychological barriers. And, finally, they were not working well in their country of origin, so why the hell should they work half a world away? …

What we needed was something simple, and more importantly, something that was consistent and our own. So I started a new grading system, beginning at 1 and proceeding one number at a time, with no subdivisions and no pre-ordained limit.
