Phillip Island Boonwurrung: Corriong, Worne or Millowl is an Australian island about 125 km south-southeast of Melbourne, Victoria. The island is named after Governor Arthur Phillip, the first Governor of New South Wales, by explorer and seaman George Bass, who sailed in an whaleboat, arriving from Sydney on 5 January 1798.
Phillip Island forms a natural breakwater for the shallow waters of the Western Port. It is 26 km (16 mi) long and 9 km (5.6 mi) wide, with an area of about 100 km2. It has 97 km (60 mi) of coastline and is part of the Bass Coast Shire.
A 640 m (2,100 ft) concrete bridge (originally a wooden bridge) connects the mainland town San Remo with the island town Newhaven.
