"After last night's concert . . . it was necessary to seek medical advice due to vocal issues Frank Ocean experienced during the show," said tour promoter Live Nation.
Ocean's first Australian tour kicked off Thursday night in Melbourne, where the singer was reportedly performing off-key, and the show closed without an encore.
The tour centered on a performance at Splendour in the Grass on Sunday, but the appearance has been canceled. Additionally, tonight's performance and two dates next week have been pulled while Ocean recovers.
