The service, to start at 6pm on Tuesday, September 20, will be presided over by the Anglican Archbishop of Adelaide.

Up to 600 seats – including 450 for members of the public – will be allocated, with the service to also be broadcast on screens outside the cathedral and live-streamed online.

Registration via the Department of the Premier and Cabinet website is required to secure a seat.

The government is also urging those who wish to view the service outside the cathedral to register their attendance, so it can gauge the expected crowd number.

According to the government, the service will “pay respect to Her Majesty The Queen and her more than 70 years of service to South Australia and the Commonwealth” after she died on Friday, aged 96.

Premier Peter Malinauskas said he anticipated the church service would draw a large crowd.

“As always, it’s hard to predict what those numbers will be, but I think it’s largely been confirmed now that the largest crowd anywhere in the country for the proclamation of the King was indeed here in South Australia,” he said.

“I anticipate there’ll be a lot of South Australians who will want to formally pay their respects to the Queen at the official state church service.

“We’re seeking to facilitate as many members of the public be able to go along and do that as we possibly can.”

It comes after the federal government yesterday announced that 2022 SA Young Australian of the Year, Dr Trudy Lin, was the only South Australian selected to attend the Queen’s state service in London.

Lin provides oral healthcare to people with disability, psychiatric conditions and complex medical conditions such as cancer. She also treats people experiencing homelessness, trauma and domestic violence.

“It is such an honour and so incredibly humbling to be selected to be a representative of South Australia and Australia,” Lin said.

“But also, I do hope that the focus is not so much of me as an individual, but me as a representative of all the other specialists and special needs dentists in Australia who work for the same cause and have their hearts wanting to create more equitable access to inclusion for the most vulnerable people in our community.”

Lin said she would fly to Sydney tomorrow to join the nine other invited Australian guests.

She said she would then fly on Prime Minister Anthony Albanese’s plane to London.

“I received a call on Sunday afternoon from the Prime Minister’s office, and they informed me that the Prime Minister requests that I attend with him to Her Majesty’s funeral in London and that arrangements would be made a pending my willingness and availability to attend,” she said.

“I took a bit of time to process, but (it was) incredibly humbling when I thought of not what it meant just for me as an individual but also what it meant for all the people whose identity resonates with something that relates to me.”
