Shoalwater Bay Military Training Area, Military training facility and heritage site in Byfield, Australia.

Shoalwater Bay Military Training Area covers about 454,500 hectares of coastal land 4 kilometres north-west of Byfield, Queensland. Its eastern shoreline has long sandy beaches and small rocky headlands backed by the high dunes of Cape Manifold and Freshwater; to the north lie tidal mudflats, shoals, offshore islands, seagrass beds and mangrove-lined creeks. Hilly and mountainous ranges cross the site, and 58 floristic communities have been recorded.

Shoalwater Bay Military Training Area was added to the Australian Commonwealth Heritage List on 22 June 2004, recognised as a large, relatively undisturbed natural system of coastal landforms and high biodiversity. Its dunefields have a history extending well over 100,000 years, probably formed from sand supplied by the Fitzroy River. The listing covers about 454,500 hectares, 4 kilometres north-west of Byfield.

The name Shoalwater Bay refers to the shallow tidal waters off the northern shore, where mudflats and shoals emerge at low tide. The place is a military training area, not a public site, so there are no visitor traditions or guided tours. Its cultural value lies in the heritage listing of 22 June 2004, which recognised the coastal landforms and ecosystems within the training ground.

The training area lies about 4 kilometres north-west of Byfield, reached via Byfield Road in the Shire of Livingstone. It is an active military installation, so access is controlled and the site cannot be toured like a park. The eastern shoreline of long sandy beaches and rocky headlands, the dunes of Cape Manifold and Freshwater, and the tidal mudflats of Port Clinton and Shoalwater Bay are the main features to orient by.

The area hosts about one-third of all Australian bird species and contains more than 50 different plant communities in close proximity. This biological variety coexists remarkably with active military use.
