Rodondo Island, Nature reserve on a granite island in Bass Strait, Tasmania, Australia

Rodondo Island is a granite island of 106 hectares in northern Bass Strait, ringed by cliffs up to 200 metres high and rising to 350 metres. Its vegetation includes Disphyma herbfield, Stipa and Poa poiformis tussock grassland, Melaleuca armillaris low closed forest, Allocasuarina verticillata low open forest, clifftop shrubland and Eucalyptus globulus open forest.

The island was discovered in 1800 by James Grant from the ship HMS Lady Nelson and named after a similar rock formation in the West Indies. It gained protected status in 1976.

The island forms part of the Wilsons Promontory Islands Important Bird Area, recognized by BirdLife International for seabird breeding populations.

The steep cliffs make it difficult to access the island by boat, so visits are heavily restricted. The best views come from boats at a safe distance or from certain coastal vantage points.

The southern water skink has been recorded on Rodondo Island and nowhere else in Tasmania, making this its only Tasmanian location. The island also hosts about 500,000 pairs of short-tailed shearwaters, roughly 2.1% of the world population.
