Gladstone Gaol Expression of Interest (EOI)

The Department for Environment and Water invites Expressions of Interest (EOI) from parties interested in activating Gladstone Gaol through innovative and sustainable proposals. 

The state heritage-listed former Gladstone Gaol operated between 1881 and 1975 as a medium security prison, and as a military detention barracks during World War II. The Gaol permanently closed in 1975, and in 1978 was reopened to visitors offering historic tours. 

The EOI process seeks proposals for tourism, commercial, community or residential opportunities that will enhance the site’s value for the community, visitors, and stakeholders.  Proposals may involve ongoing, seasonal, one-off, exclusive, or non-exclusive activations and may include lease, licence, or purchase arrangements provided they align with the strategic vision for the site.

Important Note: Purchase opportunities are available only for land located outside of the Gaol walls. The Gaol structure and the land within the Gaol walls are not for sale.
