Heron Island Reef is located near the Tropic of Capricorn. It is part of the Capricorn Bunker Group of coral reefs and islands on the southern Great Barrier Reef, one of the most biodiverse marine ecosystems in the world.

Heron Island lies 80 kilometres north-east of Gladstone on Queensland’s east coast. It is 300 metres at its widest point and 800 metres long – it spans 16 hectares at high tide and 23 hectares at low tide.

Weather and tides

Heron Island has average daytime temperatures ranging from 22°C to 30°C year round.

The reef experiences south-easterly and easterly winds averaging 11 knots to 12 knots for most of the year. Most rain falls between December and June.

There are two daily tide cycles with a maximum range of approximately three metres.

Reef flats can flood quickly on an incoming tide so check tide predictions and weather forecasts before working in the field.

The AIMS sensor on Heron Reef provides the latest weather and oceanographic observations.
