Australia would have been Campbell's final international stop on his 'Goodbye Tour' with Rogers, though doctors advised the country star that he was not up for "the very long flight that it would require" to get him here because of his battle with Alzheimer's disease.

Kenny Rogers will continue on the tour accompanied by Aussie country artists filling Campbell's big shoes.

A statement from event promoters reads: "Due to a decline in his Alzheimer's condition his medical specialists have advised that the long international flight from Los Angeles would be detrimental to his health. No one had anticipated the travel complication or impact on coming to our distant locations."
