The 45-year-old actor - who was born in Sydney - celebrated the annual holiday which marks the anniversary of the 1788 arrival of the First Fleet of British Ships at Sydney Cove with wife Deborra-lee Furness and their children Oscar and Ava at bar Refinery Rooftop.

According to the New York Post newspaper, Hugh gave a speech about his Australian pride with the iconic Empire State Building lit in Australia's colours - including blue, white and red - behind him.

The hunk entertained crowds with a performance of 'I Still Call Australia Home' - a song written and performed by Peter Allen in 1980.

Other stars at the event included Australian Consul General Richard Leather, Qantas executive Vanessa Hudson and 32-year-old businessman Ivanka Trump - who is daughter of American business magnate Donald Trump - and they enjoyed food from celebrity chef Neil Perry.
