Aidan O'Brien's dual Derby winner Australia is back in full work ahead of his end-of-season targets.

The Galileo colt has been given a break since winning the Irish Derby at the Curragh, supplementing his Epsom triumph and a fine third in the 2000 Guineas.

He is now due to drop back to 10 furlongs with the Juddmonte International at York on 20 August and the Qipco Irish Champion Stakes on 13 September identified as possible targets.

"He's back in full work and everything has gone according to plan." said O'Brien

"The boys (owners John Magnier, Michael Tabor, Derrick Smith and Teo Ah Khing) have their eyes on a couple of races - York and Leopardstown - and they will decide nearer the time whether they go to York and Leopardstown or just York or just Leopardstown."
