Sarina Beach is a late twentieth century coastal settlement, 35 km south-east of Mackay and 8 km east of Sarina. It is situated on the northern headland of Sarina Inlet which was named by surveyor William Wilson in 1869.

Sarina Beach has ready access to a sandy ocean beach and to the protected waters of the inlet. A caravan park was closed and its land fronting Owen Jenkins Drive was redeveloped as an upmarket housing estate. It has a store, a motel, a surf life-saving club, and its hinterland includes wetlands and tree-covered slopes. Its census populations have been:
