U.S. alternative rock outfit the Killers has called off three Australian dates -- including festival performances in Sydney and on the West coast -- due to a family illness.

The band has pulled the plug on tomorrow (Feb. 12) night's sold-out show at the 2,000-capacity Enmore Theatre, which was meant to serve as a warm-up for their appearance Saturday at the Good Vibrations Festival in Sydney, and the following day's GVF event at Perth's Claremont Showground.

In a statement issued today, the band said they still intended to perform at the final two legs of the Good Vibrations Festival, which roll out Feb. 20 on the Gold Coast, and the next day in Melbourne.

The Killers were the main draw on the Good Vibrations tour, whose dance-oriented bill includes Basement Jaxx, Armand Van Helden and Gossip.

The Las Vegas rockers' late withdrawal will come as a blow to organizers, who earlier in the day announced the withdrawal of British indie act Friendly Fires, who had canceled their visit to Australia because of a family emergency affecting one of the band members.
