Nundah Air Raid Shelter, World War II defense structure in Nundah, Australia.

The Nundah Air Raid Shelter is a concrete surface shelter on Sandgate Road, Nundah, designed by Frank Gibson Costello and built by Brisbane City Council around 1942. It is a standard pillbox-type structure with thick concrete walls and a heavy slab roof, now used as public toilets. It was added to the Queensland Heritage Register on 6 April 2005.

Brisbane City Council built the Nundah shelter in 1942 to a design by architect Frank Gibson Costello, after Premier William Forgan Smith's December 1941 order required 200 public surface shelters in the city. The programme produced 235 shelters, 90% complete by June 1942. Nundah was added to the Queensland Heritage Register on 6 April 2005.

The shelter stands on Sandgate Road in Nundah, one of 235 surface shelters the Brisbane City Council built for the public after the Protection of Persons and Property Order No.1 of 23 December 1941. Its wartime role ended long ago; it now serves as public toilets, so the structure is encountered as part of the street's everyday furniture rather than as a monument.

The shelter is accessible and easily found on Sandgate Road, though it functions as public restrooms today. Be aware that visiting hours may depend on the restroom operation times, so visiting during daytime hours is generally more reliable.

Only about 21 wartime shelters like this one survive in Brisbane today, making it quite rare. Its conversion to public restrooms shows how military architecture was adapted for daily use rather than demolished, a practical solution unique to the city's postwar recovery.
