Founder 

In 2014, an Expression of Interest (EOI) and tender process was initiated to provide recreational activities at Walkabout Creek Conservation Park, following changes in State Government legislation governing tourism in national parks. After a two-year process involving extensive consultation and negotiations with key stakeholders—including the State Government, Seqwater, Traditional Owners, the local community, and private enterprise—Sharpey and his business partner, Fiona Heizmann, co-founded Walkabout Creek Adventures in 2016. The business specialises in single and tandem kayaks, stand-up paddleboards, mountain bikes, and Segway tours.

Today, Riverlife operates this leisure and recreation business, offering affordable social, educational, and team-building adventures within D’Aguilar National Park at Enoggera Reservoir.
