Politicians have gathered at NSW parliament to mark the death of Queen Elizabeth II and suspend the sitting of both houses for one week.
Premier Dominic Perrottet on Tuesday moved a motion to suspend parliament for one week, as a mark of "profound respect and a deep affection" for the late monarch.
The lower house met briefly to hear Governor Margaret Beazley formally announce the Queen's death and the ascension of King Charles III to the throne.
A condolence motion addressing the new king and members of the royal family moved by the premier passed without debate.
"We the members of the Legislative Assembly of NSW, in parliament assembled, take this earliest opportunity to express our profound sorrow at the death of our late beloved sovereign, Queen Elizabeth II," Mr Perrottet said.
"And to convey to your most gracious majesty, and other members of the royal family, our heartfelt sympathies."
The premier then moved a second motion to congratulate the new monarch, before a motion to adjourn both houses was passed.
The motions passed without opposition, however there would be opportunity to debate the suspension next week when parliament returns, Speaker Jonathan O'Dea said.
Parliament House remains open for functions and events.
The NSW Greens do not support suspending parliament, with member for Newtown Jenny Leong saying politicians need to continue working for their communities.
"The cost of living and climate crises don't stop when a monarch dies, and nor should democracy," she said.
"There is so much work to be done for our communities and they must always be our priority."
