Oscar Pistorius has formally cancelled his Australian tour in the face of charges of murdering his girlfriend on Valentine's Day.
The South African Olympic and Paralympic athlete was charged on Friday with the premeditated murder of 29-year-old Reeva Steenkamp, who was shot dead at his luxury Pretoria home.
He had been contracted to compete in races in Australia, Brazil, Britain and the United States between March and May.
In what was considered a major coup for Athletics Australia, the double-amputee runner was to be the star attraction of the Australian athletics tour.
Pistorius, dubbed the Blade Runner, was scheduled to race in Australia for the first time at the Sydney Track Classic on March 9 and in Perth a week later.
