Hard to believe it, but the first Group 1 of the new season is upon us already.

The Chris Waller-trained Via Sistina carried the Yulong colours to victory in the 1400-metre weight-for-age showpiece last year and she'll have plenty of fans when she steps out again at Randwick on Saturday.

The Silver Shadow, Toy Show, Show County and Premier's Cup are the support acts at Randwick, while the Carlyon Stakes is the feature at The Valley.

At Morphettville it's Leon Macdonald Stakes day.

You'll find Australia's best form guide for Saturday's Valley, Randwick, Eagle Farm and Morphettville meetings in this week's Best Bets.

On pages 4 and 5 you'll find four-state selections from some of the nation's leading form analysts as well as our popular Black Bookers, Sectional Stars and Video Stars features.

Best Bets ($7) is on sale Thursday morning in NSW newsagents, Friday elsewhere.
