The Wunta Fiesta committee has made the tough decision to cancel next year's event.
Fiesta committee president Donna Gladman said it was a heartbreaking decision to make, but it was hoped the time could be used to plan a revamped event in 2022.
Mrs Gladman said the committee decided that even if restrictions on outdoor gatherings were lifted, it wouldn't be socially responsible to encourage a large amount of people to come together.
She said the committee also wouldn't want to have to turn people away if there were limits to gatherings.
In addition to that, the event relies heavily on sponsors.
"It's been a really tough time for businesses and we wouldn't want to put extra financial pressure on businesses that sponsor us," Mrs Gladman said.
She assured city residents the committee was committed to hosting the event in 2022.
"We're going to focus on building an amazing 2022 Wunta Fiesta," Mrs Gladman said.
"We're going to look at making some changes and making it even better."
Mrs Gladman said it was the first time the fiesta had been cancelled in more than three decades.
She said it was particularly sad that the jazz in the gardens event wouldn't be held because it was cancelled due to wet weather this year.
"That's a hard pill for us to swallow," Mrs Gladman said.
"We know people love jazz in the gardens."
The Wunta Fiesta is held annually at the end of summer and offers a mix of live music, markets, food and family friendly events.
