Twin Waters, a coastal suburb on the north side of the mouth of the Maroochy River, is 95 km north of Brisbane. It was originally part of Mudjimba and the coastal locality of Ningerry Beach (a name now discarded).

Twin Waters is mostly a canal estate built beside the Novatel Resort golf club (1990) and the resort hotel which is nearer the beach and a coastal lagoon. The lagoon is enclosed by the Maroochy River conservation park, and the entry of canal waters to the Maroochy River is regulated by a weir.

Twin Waters, including a substantial residential area around the canals, was formed in little more than the 1990s decade. Very little of the pre-residential land uses remain, other than the conservation area and a youth camp taken over by the service association Apex.

The Twin Waters retirement village over the road from the Novatel golf club has a bowling green, leisure centre, cinema, auditorium and an outdoor pool. Accommodation is provided in houses, apartments and penthouses. The Twin Waters shopping centre is also nearby.
