Tributes have flowed in South Australia for actor and comedian Barry Humphries, who had a "close connection" with the state.
The lights will be dimmed at today's performances of Come From Away today at Her Majesty's Theatre and The Rocky Horror Show at the Festival Theatre, in tribute to Mr Humphries who has died aged 89.
Floral tributes were also left outside Her Majesty's Theatre, which Mr Humphries held a long-running association with and had described as his favourite in the country.
Adelaide Festival Centre chief executive officer and artistic director Douglas Gautier said Mr Humphries first performed at Her Majesty's Theatre in 1953 at the age of 19.
"So for him it was very much a debut," he said.
Mr Humphries went on to perform his own shows at the theatre 11 times until his last in 2013.
He was also the patron of Her Majesty's Theatre redevelopment fund, fronting the campaign to fill a funding shortfall and even casting a careful eye over design plans.
"Without Barry up the front there, really telling people why this was important, this project wouldn't have happened," Mr Gautier said.
Mr Humphries returned to Adelaide in 2015 as the artistic director of the Adelaide Cabaret Festival in 2015, which Mr Gautier described as one of the "most successful festivals to date".
"Everyone I think respected his work, particularly with cabaret ... so lots of people from all over the world said, 'We'll come to this festival because Barry Humphries is directing it'," he said.
Mr Gautier also said Mr Humphries was a "great mentor" to many South Australian performers during his tenure as festival director.
South Australia's arts minister Andrea Michaels also paid tribute to Mr Humphries, saying he had a "close connection" with the state.
"He's made a huge contribution to South Australia's arts community," she said.
"He's an incredible talent and his passion for comedic theatre ... is second to none, and we really do value his contribution to his arts and culture in South Australia and he will be missed."
ABC radio presenter Peter Goers who said he had known Mr Humphries for 40 years, said the entertainer "loved Adelaide" and loved Her Majesty's Theatre.
Mr Goers said the nation would be sharing his "grief and loss" at the news of Mr Humphries's death.
"I'm really gutted," he told ABC Radio Adelaide's Spence Denny on Sunday.
Mr Goers said Mr Humphries was "the greatest performing artist this country has ever produced".
"A man of genius intellect, and someone who will never be forgotten," he said.
