Kylie Minogue tickets were sold out within 120 Seconds.
The tickets for the KylieX2008 shows in Sydney and Melbourne (AUSTRALIA) in December went on sale at 9am but were gone in record time.
The pop superstar has arranged a second concert in each location, which went on sale at 9.45am today.
Promoter Michael Gudinski said Kylie fans were in for a treat.
"Kylie's X2008 tour is her biggest production yet," he said.
"She continues to lift the bar for artists everywhere with the size and quality of her shows."
Minogue recently wrapped up her 53-date European tour, which saw the $A20 million KylieX2008 show travel to 21 countries.
More than half a million people have seen the two-and-a-half-hour show, which features IMAX-sized video screen and floor screens, dazzling Jean Paul Gaultier costumes, and production to rival her
last visit to Australia on the 2006 Showgirl Tour.
