Group One racing for the Australian season draws to a close with the Tattersall's Tiara at Eagle Farm.

The Ciaron Maher-trained Azkadellia is the early favourite for Saturday's fillies and mares' feature over 1400 metres ahead of acceptances and the barrier draw on Wednesday morning.

Azkadellia got the green light to take her place in the Tiara after Maher watched her work at Eagle Farm in Brisbane on Tuesday morning.

Winner of the Group One Queen Of The Turf Stakes in Sydney during the autumn, Azkadellia finished second in the Doomben 10,000 before failing in the Stradbroke Handicap as favourite.

Azkadellia and the Henry Dwyer-trained Robert Sangster Stakes winner Precious Gem are the only Group One winners among the 23 nominations for the Tiara which has a field limit of 17.

Chris Waller is expected to make a decision on Wednesday morning whether three-year-old Tsaritsa runs in the Tiara or tackles the Listed Daybreak Lover against her own age.
