The country's best colts and geldings get their chance at Group 1 glory with the $1 million Caulfield Guineas (1600m) in Melbourne and the $400,000 Spring Champion Stakes (2000m) at Royal Randwick.

Guineas favourite Long John is out to avenge his last-start third behind Eclair Big Bang and the impressive El Roca in the Guineas Prelude, while Prince Harada has to contend with barrier 12 on his home track as he tries to live up to the famous bloodlines of his sire Haradasun.

Atlantic Jewel suffered her first career defeat to It's A Dundeel in the Underwood Stakes last start and has the chance to prove she can win over a staying distance in the Group 1 Caulfield Stakes (2000m).

At Randwick, it's a wide-open Spring Champion Stakes as the three-year-olds test their stamina levels over the 2000m.
