Outstanding mare Streama is the new favourite for the Group One Doomben Cup, the race likely to be her swan song.

The five-year-old won Saturday's Group Two Hollindale Stakes (1800m) at the Gold Coast to record her first victory since the George Main Stakes in the spring.

Her trainer Guy Walter said she deserved to go out with another Group One win.

"She has been a great mare," Walter said.

"I was very proud of her Hollindale win. She has been a lovely horse to train.

"She has always been sound. The wet tracks haven't helped her this autumn and I was worried about the heavy track at the Gold Coast but she was too good.

"She deserves a chance at the Doomben Cup which could be her last start before she goes off to be a brood mare."

A home-bred raced by the Coghlan family, Streama has won nine of her 33 starts so far and earned more than $2.3 million.

Her wins include three at the highest level, the 2011 Flight Stakes, 2012 Australian Oaks and the 2013 George Main Stakes.

Walter has also recently farewelled four-time Group One winner Appearance from his stable.

The five-year-old was retired by Sheikh Mohammed's Darley operation when she injured a leg in training.

She was unbeaten in three autumn weight-for-age starts culminating in the Group One Canterbury Stakes (1300m) in March.

Streama is at $3.50 with the TAB ahead of Akzar at $4.50 and Junoob at $5.50.

Mr O'Ceirin, the horse Streama chased down to win the Hollindale is at $6.50 alongside Leebaz who is not a confirmed starter in the 2000m race on May 17.

Senior training partner John Hawkes said he would assess Saturday's Hawkesbury Gold Cup winner over the next week before deciding whether to press on or give him a break with a view to the spring.

A lightly-raced son of Zabeel, the four-year-old has won six of his nine starts but has so far only been tested up to the 1600 metres of the Group Three Hawkesbury feature.
