Marie Bashir has given her final Australia Day address as governor of NSW in a ceremony marking the end of official Sydney festivities for the national holiday.
Tens of thousands of spectators packed Darling Harbour on Sunday night to watch the day's celebrations peak with a dazzling fireworks display.
Professor Bashir, who is set to retire in September, sailed into Cockle Bay aboard the Admiral's Barge before taking a lap of honour in front of cheering children waving Australian flags.
She told the crowd Australia Day was an opportunity to rejoice and give thanks but also to commit to helping those who were doing it tough.
"We should not slip into complacency, for there is still much to do to address the challenges of those who need our additional support: the marginalised, those who are coping with poverty," Prof Bashir said.
"As we have done in the past, we should meet those challenges with joy and with success."
Indigenous footballer Adam Goodes, who on Saturday was named 2014 Australian of the Year for his leadership in the fight against racism, delivered a video address.
The 34-year-old spoke about the hard work, discipline and sacrifice it took for him to go from country kid to AFL superstar and said he hoped others could follow in his footsteps.
"I was shy growing up. I've learnt over time, and a large part of that learning is about standing up for things I believe in," Goodes said.
"I really hope people are inspired and find the courage to stand up for themselves in the way that I was able to do."
