No. 208 Radar Station RAAF, Military radar station in Catherine Hill Bay, Australia

No. 208 Radar Station RAAF has two concrete above-ground igloo-shaped bunkers, each with a square turret on the seaward side, and two sets of four concrete footings that once held 44-metre timber aerial towers. The footings and bunkers are placed symmetrically across an east–west axis on a ridge 93 metres above sea level.

Established in February 1943, this Royal Australian Air Force radar facility monitored enemy aircraft during World War II as part of the Advanced Chain Overseas network. The station played a critical role in air defense operations along Australia's eastern coastline.

Operators at the station were WAAAF women, who read aircraft movements on an eleven-inch cathode ray tube and worked the goniometer to fix direction, elevation and distance. RAAF mechanics serviced the relay switches and aerials, climbing the towers to do so. At formation the unit had 41 personnel, peaking at 54 in May 1943.

The site requires a steady walk over uneven ground, and visitors can access the bunkers directly while exploring the coastal paths. Best visited during dry weather to avoid slippery conditions and stronger coastal winds.

The station consumed substantial electrical power, with a dedicated bunker housing backup generators to maintain uninterrupted monitoring operations. This backup system was vital, since any power failure would have compromised air defense capabilities during wartime.
