In 1925 some of land around Mount Kaputar were declared a Reserve for Public Recreation. Two years later, a trust, known as the Mount Kaputar Trust, was formed to give guidance on managing the park. The area was expanded to and proclaimed a full national park in 1959. Eight years later, in 1967, the Fund relinquished the duties of controlling the park to the newly established National Parks and Wildlife Service, and the park is still administered by a regional advisory board.
