"I am deeply, deeply saddened to tell my Australian fans, I have to cancel my Australian tour," Smith wrote in an Instagram update. "I have been vocally exhausted for a while now however last night in Sydney I had a small hemorrhage on my vocal cords. The doctors have told me I need to fully rest until my vocal chords have healed, otherwise this could become a huge long-term issue. I am so sorry to all who have bought tickets, I truly am. This kills me."
Smith's sold-out shows in Sydney, Melbourne, Adelaide and Perth have all been canceled, as well as a scheduled appearance at the TV industry's annual Logie Awards on Sunday night. However, he reassured fans that all of the canceled shows will be rescheduled for December.
"I love you all and I am so sorry x please keep your eye on my Facebook/Twitter/Instagram for re arranged December dates x," he also Instagrammed.
No word yet on if he will cancel his upcoming Asia tour as well, which is scheduled to kick off on May 7 in Tokyo.
