Saltwater Creek winds through the back of Helensvale and Monterey Keys before joining Coombabah Creek and then the Coomera River, and this ramp on Condamine Crescent is its one public launch. The state register records a single lane, no facilities and no lane or parking detail beyond "unmarked"; in practice it is a suburban park ramp used by kayaks, tinnies and the occasional small trailer boat, and parking is never a problem because hardly anyone comes.
The creek is tidal but a long way from the sea, and the tide here runs about two hours behind the Seaway, so read the tables with that in mind. It is narrow, sheltered and fishes quietly for flathead around the railway bridge and the odd trevally, with a small side creek linking through to the upper Coomera. It is not a place for a big boat.
For a proper launch onto the Coomera, use Tallawood Road or Oxenford. Marine Rescue Queensland Gold Coast monitors VHF 16.
