Mike Hewson: The Key’s Under the Mat

What to Expect

Step into an extraordinary underground art park where creativity meets play. Mike Hewson’s exhibition transforms the Nelson Packer Tank into a vibrant, interactive space filled with monkey bars, swings, a real sauna and steam room, and a water zone to cool off. It’s a place where visitors of all ages can explore, perform, and make memories together.

This is not just an exhibition but a lively sculptural neighbourhood that invites participation and discovery. Bring your barbeque gear and enjoy the working barbeques on site, making it a perfect outing for families looking for a fun and engaging day.
