In-form Brisbane trainer Liam Birchley will this week map out spring campaigns for star two-year-olds Blueberry Hill and Hardline.

In less than a week, Birchley has produced six winners from 10 starters beginning with Royal Rocket in Wednesday's Ramornie Handicap.

Blueberry Hill, who won the Group Two Champagne Classic during the winter, is back in Birchley's stable after a break and is looking well.

"I still haven't decided exactly which way to go with her," Birchley said.

"One option is the Golden Rose. It is at 1400 metres which should suit her as an early season three-year-old."

Birchley said he was also considering taking the filly to Melbourne for the Thousand Guineas.

"But I am not convinced she is a 1600 metre horse at this stage of her career. I will see how she comes along first," he said.

Hardline, who won the Karaka Million in New Zealand, is also likely to head south but Birchley is still to map out his campaign.

"He came back into the stable on Monday and we will have to assess the options with him," he said.

Rock Royalty is another who has put himself in line for better races.

"He surprised me with the ease of his win. There might be something a bit better than we thought for him in the spring," Birchley said.

Birchley has a different problem with Saturday's Doomben winner Headwater Country, a half brother to Blueberry Hill.

Stewards quizzed Birchley about the win after Headwater Country had run 12th at his previous start at the Sunshine Coast.

Birchley told stewards he too was puzzled by Headwater Country.

"One day he runs last and the next he wins. You never know which one will turn up," he said.

Fellow trainer Kelly Schweida is also adopting a wait and see approach with Golden Falls who came from last to finish third at Doomben on Saturday.

Jockey Glen Colless reported Golden Falls had failed to travel at any stage on a track made shifty by afternoon showers.

"I know you can make excuses and she didn't seem to stretch out like she did at her previous win," Schweida said.

"But they were B graders and you would have liked her to have won," he said.

"She is a stakes class filly but whether we chase black type this campaign or her next I will decide in the next few days."
