As a sign of mourning, the National Australian National Flag and flags alongside it were flown at half-mast until the funeral. Flags returned to full-mast at 8am on Tuesday 20 September.

In acknowledgement of the passing of Her Majesty The Queen, Government House hung a hatchment for Her Majesty Queen Elizabeth II at the gates of Government House for 2 weeks.

The hatchment was designed by the Australian Heraldry Society. The design was a combination of the arms assigned to South Australia by Her Majesty The Queen in 1984 and the sovereign’s ‘helm and mantling’.

A tribute site was established within the grounds of Government House from 9–22 September. Members of the public were invited to leave tributes in honour of Her Majesty The Queen.

A number of state government buildings were illuminated at night, and Her Majesty The Queen's portrait was projected on Government House until 22 September.

Condolence books were available at Government House, Adelaide Town Hall, City of Playford Civic Centre and offices of local Members of Parliament (MPs), for members of the public wishing to leave a message for The Royal Family.

The messages left in the condolence books were collated and sent to The Royal Family from the people of South Australia.
