During these formative years the principles of the Quaker faith and a love of the outdoors helped shape the future direction of his life.

In his spare time he immersed himself in bushwalking and skiing, and from 1928 began undertaking major journeys into remote areas of the state.

Within a decade Jack's passion for adventure and wild places made him a desirable choice as a member on National Park Boards.

In 1958 he took up a full-time appointment as Inspector of Scenic Reserves for the Scenery Preservation Board (forerunner to the National Parks and Wildlife Service).

A great raconteur, Jack drew on an inexhaustible fund of bush experiences and personalities as he dispensed billy tea round the campfire.
