Leading Scone trainers Greg Bennett and Rod Northam dominate the 24 entries for the local heat of the Country Championships with four nominations apiece.
Sunday's 1400m-race is the second regional qualifier for the $400,000 final in April with the first at Goulburn a day earlier.
The Bennett-trained Invienna is the top-rated horse in the entries as she tries to reverse her unplaced run behind stablemate All Summer Long in a Highway Handicap at Randwick last Saturday week.
The first and second placegetters on Sunday gain automatic entry to the final at Randwick on April 2 with a wild card race at Muswellbrook a week earlier the last chance to qualify.
