"Today each of you will be endowed with the same rights, opportunities, privileges and responsibilities as every other Australian … no matter how long they’ve been here," he said.
"You will be given the inheritance of our history and the promise of our shared future.
"But you don’t come to our national story empty handed, either.
"As like so many before you, you add your threads to Australia’s rich tapestry. You now write your own chapters in Australia's story."
He lauded Australia as the world's most "successful" multicultural nation and thanked the new citizens for their "great expressions of love for our country".

"I pay homage to the people of the Eora nation who suffered the first impact of colonisation on behalf of all Aboriginal nations."
NSW Governor, Margaret Beazley, said the pandemic had highlighted the fact Australians needed to act as "one mob".

"Let us learn from these past difficult years, let's celebrate the good and let's walk together on this path as WugulOra (one mob)," she said.

Police said the peaceful crowds had grown into the tens of thousands.
Overnight in Melbourne, a statue of Captain Cook in St Kilda was vandalised with red paint in an act of protest which Victorian police have described as "absolutely ridiculous".
"Whilst we understand people have certain views about this day, we always ask people to be respectful and blatant criminal activity like that will not be tolerated," Victoria Police Assistant Commissioner Glenn Weir told Channel Nine.
Another Captain Cook statue in Edinburgh Gardens, in the inner Melbourne suburb of Fitzroy North, was also covered in red paint overnight.
The Australia Day parade which usually runs through Melbourne's CBD was cancelled for a second consecutive year, while a planned Invasion Day rally has also been scrapped.

"I'm just grateful that my parents chose Australia because we had the choice of either South Africa, America or Venezuela, and Australia is the best country," she said.
"Even though what we're going through at the moment, I'm still grateful every day … we've still got the best country."
