The 2020 event has been pulled, but over 30 artists have committed to 2021.

Legendary music festival Bluesfest will not take place over Easter this year due to the Public Health Act order instated on Monday by the New South Wales Government in response to the coronavirus pandemic.

It's the first time in 30 years that the event will not take place.

The festival, which drew more than 105,000 people to the Tyagarah Tea Tree Farm across its five days in 2019, was set to feature a bill that included US megastars Dave Matthews Band, local icons Crowded House and punk legend Patti Smith.

In a statement released Monday, festival director Peter Noble said it was "obvious" the festival, set to happen from Thursday 9 to Monday 13 April, couldn't go on.

"We are heartbroken as we believe we were presenting one of the best ever bills of talent for you," he said.

"We are now working through how to move forward and to give you details. I thank you for allowing us enough time to get everything in place for the best possible outcome for everyone."

UPDATE: Peter Noble issued a public statement on Thursday afternoon, confirming that Bluesfest will go on in 2021.

Noble said that he has a commitment from many artists on his 2020 line-up to perform at next year's event.

"We will find a way to continue and present in 2021," he wrote.

"I am a veteran, having been in this incredible industry since the 60s. I have never experienced such a dire situation. As a premier event we need to present another Bluesfest not only for ourselves but also for the entire entertainment industry to see that there will be a brighter day, and that as an industry we will come back from this.

"We are humbled by the incredible response we have received by the outpouring of love from our ticket-holders, music industry and importantly from our local community.

"We are in discussions with all the agents representing the artists who were due to play this Easter on what has been our greatest bill ever.

"Whilst we currently don’t know ‘who’ all our headliners will be in 2021, we have received feedback from over 30 artists off this year’s bill confirming they are ready to reschedule for 2021. Their level of support and goodwill is inspiring and I foresee a great event to come.

"2021 will be the year for everyone who cares about the arts, music and the entire entertainment industry that we all love, to come out and show their support for each other. We call on our industry, the musicians, the agents and the managers to get in touch with us and help us show the solidarity of strength that we have as a combined force.

"We are all in this together, and together we will go on and get through these troubled times. Since the ban was announced last Sunday we have gone from having a deep case of the blues to presenting the blues for you again in 2021. This much we know.

"Time is a healer and one day this will be behind us. It has not been easy and we are still in what is a lengthy process working out the details. Representatives from our insurance companies have advised that our claim is being processed and ticket refunds or the option to roll over to Bluesfest 2021 will be available soon.

"We will constantly keep our patrons updated in this area and thank them all again for the patience they have shown.

In the meantime, we wish you all good health and to remain strong and positive in these very trying times. See you at Bluesfest."

Earlier, New South Wales Health Minister Brad Hazzard used special state powers to force the immediate cancellation of public events with more than 500 people.

The mass of cancellations of tours and festivals is having a dire impact on the Australian music industry, which has been almost shut down in recent days.

More than $25 million in wages was reported in one day after industry groups asked artists, managers, bookers, venue owners, and others to self-record their lost income.

Both the live performance industry and the arts workers union, the MEAA, are asking the Federal Government for a hand to get through this difficult time. The groups are set to discuss the issue on Tuesday.
