It's A Dundeel has been the subject of strong interest from punters ahead of Saturday's $4 million Queen Elizabeth Stakes (2000m) at Royal Randwick.

Although yet to win a race this campaign, his fast-finishing second behind Silent Achiever in The BMW (2400m) has been followed by a stream of money to suggest he can breakthrough in the biggest race of the carnival.

"We are holding five times the amount on It's A Dundeel compared to the favourite Carlton House," said's Shaun Anderson.

Carlton House, who was narrowly beaten by Silent Achiever in the Ranvet Stakes, is $3.70 with Silent Achiever at $4.60 and It's A Dundeel at $5.

Doncaster Mile winner Sacred Falls has firmed to $8, the same price as stablemate and runner-up in last Saturday's $3 million race Royal Descent.

Waller's other runners Boban and Hawkspur are next in betting at $11. (racing network)
