Rock band KISS have cancelled their Newcastle Supercars concert and the rest of their Australian tour, citing illness to singer Paul Stanley.
Promoters One World Entertainment and TEG Live said on Friday that they and the band were "absolutely gutted" by the news and "sincerely apologise" to fans.
Supercars has cancelled the entire concert scheduled for Saturday, November 23, at No.1 Sportsground and will refund the concert portion of race tickets.
The Screaming Jets were scheduled to play on the bill as a support act.
Supercars said the "matter is completely out of our hands and we are extremely disappointed for our fans".
The promoters announced this week that doctors in America had advised Stanley to rest due to a bad case of flu, prompting the rescheduling of the tour's first show in Perth to the end of the run and the cancellation of the New Zealand leg of the tour.
"It was hoped the extra few days' rest would allow Stanley the chance for a complete recovery so the tour could proceed as planned," they said in a statement.
"However, unfortunately this has not occurred. Stanley has an additional infection in his throat requiring complete vocal rest and medication for at least two weeks and possibly longer."
Paul Stanley said: "Words cannot begin to convey our massive disappointment in having to cancel our End Of The Road tour of your incredible country. Our connection to you is unparalleled and decades deep.
"We waited as long as we could and held out hope to the last minute that my situation would clear up and we would be able to march forward.
"Doctor's orders ultimately have taken precedence and finally we now find ourselves with no choice but to surrender."
One World Entertainment and TEG Live said: "We are devastated with the cancellation of the Australian tour.
"We've been in constant contact with the band in the past few days hoping for a positive outcome. We know how much fans were looking forward to the tour. We send our best wishes to Paul for a speedy recovery."
The tour also included a "concert at sea" near Port Lincoln, South Australia.
As part of accommodation company Airbnb's launch of Animal Experiences, to help set a new standard for animal tourism, the band will play offshore on the deck of a local tourist charter boat.
It was a sellout. No surprise the eight tickets went quickly.
It is with sadness that we inform our fans that KISS has cancelled their upcoming tour of Australia which includes the scheduled performance as part of the Newcastle 500 concert scheduled for Saturday 23rd November 2019.
As a result, the concert featuring performances by both KISS and The Screaming Jets has been cancelled.
This matter is completely out of our hands and we are extremely disappointed for our fans.
While the decision is out of our control, we sincerely apologise to The Screaming Jets, Supercars fans and KISS fans alike.
