The 70-year-old musician, the last surviving member of the iconic band of brothers, was due to play one concert in Auckland, New Zealand and had seven Australian dates on his In The Now world tour scheduled for April (17), including an appearance at the Byron Bay Bluesfest..
However a statement posted on the tour's promoter Live Nation's website announced that Gibb would no longer be coming to the countries "due to a change in international commitments".
"Barry Gibb and Live Nation regret the disappointment to ticket holders,” the statement reads.
The concerts will not be rescheduled, with all ticket holders for dates except Bluesfest able to claim full refunds.
Ticketholders for Gibb's day of Bluesfest festival will be able to get their money back, however the event's director Peter Noble wrote on the Bluesfest's Facebook page that he already had an "amazing artist" ready to take the Stayin' Alive singer's place.
Gibb's cancellation of his Bluesfest appearance comes just weeks after another big name, Neil Young, pulled out of the event and cancelled his own tour of Australia.
