Australian superstar Black Caviar is 'bright as a button' following her 30-hour flight from Melbourne, according to her vet Peter Angus.

The six-year-old mare, unbeaten in 21 races, arrived in England on Thursday and will be based at Jane Chapple-Hyam's Newmarket stable from where she will be aimed at the Diamond Jubilee Stakes at Royal Ascot on June 23.

Angus, who accompanied Black Caviar on her epic flight, said: 'After a journey like this they can be so tired that sometimes their eyes are dulled, but she's as bright as a button.

'She seems to have eaten and drunk on the flight and is in very good condition.'

The three-year-old won the Kentucky Derby and Preakness Stakes in May and would have been attempting to become the 12th US Triple Crown winner and the first since the Steve Cauthen-ridden Affirmed in 1978.

Trainer Doug O'Neill said: 'Pulling him isn't tragic but it's a huge disappointment.'
