Joseph O'Brien believes he can manage the 8st 12lb weight allotted to Australia in Wednesday's Juddmonte International at York.
Should the jockey's father Aidan give the Investec Derby winner the go-ahead for the Knavesmire, Australia would be dropping back two furlongs from his most recent appearance in the Irish Derby.
Two years ago, O'Brien jnr had to miss the ride on Camelot in the Prix de l'Arc de Triomphe because he could not manage 8st 11lb.
After winning on Qualify at Dundalk, when he put up 1lb overweight on a horse scheduled to carry 9st, the jockey was asked about Australia.
He said: "I can do the weight."
