Each year, Ferrython completely transformers Sydney Harbour as four luxury liners compete in a race across the Harbour.

Ferrython is the only Australia Day event on the harbour and Variety is giving people the unique opportunity to be part of the historic race, as the only Ferry open to the public. All money raised is being donated to sick and disadvantaged kids.

While the race only goes for 30 minutes the festivities will continue long into day, with a four hour on board extravaganza including entertainment, with a DJ spinning the latest tunes and MC. Families can even bring their own picnic hamper on board. It's the perfect way to celebrate Australia Day for all ages.
