In 1996 a Steering Committee was formed to manage the future of the underground hospital, representing the owners, heritage conservation organisations and corporate and community representatives. This conservation strategy was funded by the National Trust with support from the Department of Environment.
The hospital, built entirely underground, is currently thought to be unique in Australia. As such, the site possesses considerable archaeological significance, with potential to yield evidence about 1940s medical and nursing technology and about local improvisation during wartime. It is also important as an example of mid-20th century mining technology, and the skill and speed of Mount Isa miners of the period.
