Frank Ocean has canceled the remaining dates of his tour Down Under after suffering a tear to one of his vocal cords.

On Thursday night, the R&B singer launched his series of shows in Melbourne, however he battled throat problems throughout his first performance, and sought medical help as soon as he stepped off stage.

The 25 year-old singer was diagnosed with a vocal cord tear and he has axed the rest of his Australian tour, including planned performances in Sydney and at the Splendour in the Grass music festival.

A statement from concert promoters Live Nation reads, "(We) regret to announce that Frank Ocean's remaining Australian dates will not go ahead due to illness. After last night's concert in Melbourne at Festival Hall, it was necessary to seek medical advice due to vocal issues Frank Ocean experienced during the show.

"It has subsequently been confirmed that Frank has suffered a small tear to one of his vocal cords and has received medical advice that he must rest his voice. This makes the completion of his remaining Australian dates impossible."

The dates will not be rescheduled, but tour bosses hope to bring Ocean back to Australia "as soon as is practical."

The Pyraminds hit-maker is due back on stage at the Osheaga Festival in Montreal, which kicks off in August, but it is not yet known whether he plans to go ahead with the show.
