Shag Island is a low island located at the mouth of Fisherman's Bay in Spencer Gulf, South Australia. It is approximately 22 ha (54 acres) in size[1] with a peak elevation of approximately 4 metres (13 feet).[2] It is uninhabited by humans but is home to thousands of cormorants which roost and breed there. It is also an important nursery-ground for fish.[3] In April 2013, the discovery of several sick and dead cormorants near Fisherman's Bay raised public concerns for the health of the Shag Island colony.[4] The discovery coincided with significant fish and dolphin mortality events around the state, mostly concentrated in Spencer Gulf and Gulf St. Vincent.[5]


The following birds have been recorded at Shag Island: great cormorant, little black cormorant, pied cormorant, little pied cormorant, red-necked stint, sharp-tailed sandpiper, red-capped plover, banded stilt, bar-tailed godwit, grey plover, common greenshank and masked lapwing.[6]
