The Group 1 action heads to Queensland for the first time this season on Saturday as the elite sprinters match motors over 1200 metres in the Doomben 10,000, where smart local colt Grafterburners will be looking to graduate to top-level success.

Support races at Doomben include the Group 2 Spirit Of Boom Classic for the two-year-olds, the Group 3 Rough Habit Plate for three-year-olds, the Group 3 Chairman's Handicap for the middle-distance types and two listed races.

Scone takes centre stage in NSW with the running of five stakes races led by the Group 3 Dark Jewel, while the Victorian winter series heats continue as racing returns to Flemington.

You'll find Australia's best form guide for Saturday's Flemington, Scone, Doomben 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.
