The postponement of The Rolling Stones Australian and New Zealand tour could reportedly cost the band as much as US$10 million (NZ$11.7 million).
Mick Jagger, Keith Richards, Ronnie Wood and Charlie Watts were set to kick off their hotly anticipated tour in Perth last Wednesday.
But the Australasian leg of the 14 On Fire world tour was postponed following the suicide of frontman Mick Jagger's girlfriend L'Wren Scott.
Frontier Touring announced the postponement of the tour a day after Scott's death.
Industry sources have told Billboard magazine the postponement could cost up to $10 million.
Billboard says the figure includes deposits on venues, storage and transportation of gear and lost revenue.
"Moving a tour the magnitude of a Stones outing is an epic, expensive affair, potentially involving millions of dollars in travel, transportation and other expenses.
"While some production work would have been done on the ground, the band had 60 trucks on hold to transport its equipment, and just chartering the gear could have cost as much as US$250,000," the report says, citing sources.
Australian promoter Michael Gudinski, whose Frontier Touring is presenting the band with AEG Live, has told The Hollywood Reporter The Stones had sold more than 150,000 tickets.
Talks are underway to bring the band back to Australia and New Zealand in October/November.
Meanwhile, the Stones have announced they will play Paris' Stade de France in June for the first time since 2007.
The band will play a single gig in France's national stadium in Paris on June 13 as part of the 14 On Fire tour, according to a statement from their French promoter.
The Stones already have a string of dates planned across Europe for June, including in Germany, The Netherlands, Belgium and Italy.
Their promoter says several more European concerts will soon be announced for May, June and July.
