All five P&O ships departed Sydney Harbour on Wednesday night with special performances from Jessica Mauboy, The Veronicas, Justice Crew, Samantha Jade and Stan Walker.

There was also a spectacular fireworks display with guests onboard the ships decked out in white and grooving to music from Australia’s biggest stars.

It was just one of the many events that were on today – in the morning, the five ships made their way into Sydney Harbour and the new Pacific Aria and Pacific Eden were christened by their godmothers, Ms Mauboy and former Home and Away star and radio DJ, Kate Richie.

And in the afternoon, media were given a tour of the newly refurbished Pacific Aria.

In the evening, thousands of guests had an exclusive concert which was followed by a fireworks display.

Check out some of the highlights of the evening.
