Zac is a Level 2 APSI qualified cross country ski-instructor and the K7 Adventures Koscisusko Ski School Director. He first strapped on a pair of cross country skis in 1976 and then somehow managed to gasp his way around the NSW 30 km Championships, finishing a distant last. Undeterred he came back for more, eventually qualifying as a cross country ski instructor in 1989. Zac was active as an instructor and backcountry guide for the Defence Force adventure training program for many years, exploring every corner of the National Park in the process. He is still a regular instructor for the Army and Navy cross country ski and biathlon teams and in recognition of his significant contribution, Zac was made a life member of the Defence Force Cross Country Ski Association. When not instructing at Perisher or Dinner Plain, Zac spends his remaining time competing every year at the World Masters Cross Country Ski championships as well as undertaking his quest to become a Worldloppet master by competing all major ski marathons around the globe. Zac is also an accomplished high altitude mountaineer, having been on 15 expeditions to the Himalaya (including two to Mt Everest) and 12 to New Zealand. His ascents include five summits above the magic 8000 metres in altitude. Zac is also known to occasionally go over to the “dark-side” when he alpine skis in between Masters World Cup races.
