The Melbourne Royal Show will start as planned next week but with some small changes to honour Queen Elizabeth II.
The 11-day event kicks off at the Melbourne Showgrounds on September 22, which also falls as the national day of mourning for the Queen.
To acknowledge Her Majesty's death, there will be a minute's silence at 11am along with an official ceremony.
Organisers are also planning ways for visitors to acknowledge the Queen and write condolence messages to the royal family, the show's chief executive Brad Jenkins said.
"Melbourne Royal received permission to use the word 'Royal' in title in 1890 and has a long and proud history of acknowledging and celebrating Her Majesty Queen Elizabeth II," Mr Jenkins told AAP in a statement.
"This proud tradition will continue on Thursday."
Thousands of people are expected to flock to this year's Melbourne Royal Show after a two-year hiatus due to the COVID-19 pandemic.
Children aged under 14 will gain free admission to enjoy the revamped program of food, rides, live entertainment and showbags.
Show organisers have also introduced stringent biosecurity measures to eliminate the risk of foot and mouth disease.
The show runs to October 2.
