Point Cartwright Light, Lighthouse at Point Cartwright, Queensland, Australia.

Point Cartwright Light is a white hexagonal tower that rises 34 meters above the southern headland at the Mooloolah River entrance. The structure stands on a natural promontory with sweeping views over the ocean and coastline from its location.

Point Cartwright Light was built in 1978, the sixth of seven concrete towers the Commonwealth erected between 1964 and 1979, after Cape Capricorn, New Caloundra, Point Danger, New Burnett Heads and Fitzroy Island lights. It replaced New Caloundra Light of 1967, which by 1978 was obscured from some angles by taller buildings in Caloundra. The light was automatic from construction and never staffed.

The light's red sector, shining from 088° to 180°, guides vessels into Mooloolaba Harbour, while the white sector marks the entrance to the North West Channel toward Moreton Bay and the Port of Brisbane. The tower has run automatically since 1978 and was never staffed.

Walking trails around the lighthouse provide access to multiple viewing platforms with ocean views. The best time for whale watching is during migration season when you can see whales passing from the platforms.

The white flashes are rated at 310,000 candela, but the red ones only 2,100 candela, produced by a filter and a red plexiglas screen. The red sector, from 088° to 180°, guides vessels into Mooloolaba Harbour, while the white sector covers 180° to 345° for the North West Channel. The source is a 200 Watt sealed beam array on mains power, backed by a diesel generator and batteries.
