Phillip Island will continue to host a round of the World Superbike Championship through to 2017 after agreeing an extension of its contract.

The Melbourne circuit was already contracted to host the Australian round until 2014, but has now signed an extension that will see it remain on the calendar from 2015 to 2017.

"The Government recognises the importance of the World Superbikes as part of Victoria's regional major events calendar and I am thrilled to announce another three years - which means another three years of economic stimulus and promotion of Phillip Island through national and international media and broadcast exposure," said Speaker of the Legislative Assembly and Member for Bass Ken Smith "

One of the most popular circuits on the calendar, Phillip Island - which hosted its first WSBK round in 1990 - has become the traditional season opener for WSBK since 2009.

For Dorna managing direct Javier Alonso, there was little hesitation in ensuring Phillip Island remains the home of motorbikes in Australia.

"Phillip Island is a special place, a unique track in a unique location. The island always delivers intense competition, with its long straight and fast flowing turns. It's a great test for riders and a challenge for teams. The result is thrilling racing for fans whether they are cheering trackside or watching on television from anywhere around the globe."
