The immediate future of European stayer My Quest for Peace will be known this week.
A decision on whether the five-year-old remains in Australia or returns to the northern hemisphere hinges on whether he runs at next month's International meeting in Hong Kong.
My Quest For Peace was one of a group of highly-rated runners brought to Australia for the spring carnival by OTI Racing.
He chalked up two successive victories at Goodwood in England before finishing fifth in the Caulfield Cup and 10th in the Melbourne Cup.
OTI Racing's Terry Henderson said My Quest for Peace would "possibly" remain in Australia.
"We'll have our mind made up for us by whether he gets an invitation to Hong Kong," Henderson said.
One possibility is that the horse runs in Hong Kong before returning to Europe.
"We just don't know," Henderson said. "There are scenarios there that we have to work out."
The future of two of the syndicate's other stars, Ibicenco and Gatewood is clearer.
Ibicenco rounded out the spring carnival nicely for OTI when he took out the Listed Sandown Cup (3200m) on Saturday.
He will now be prepared by leading Caulfield trainer Peter Moody who turned Manighar into a multiple Group One winner after he had languished in England two years ago.
Henderson said Ibicenco had a similar profile to Manighar.
"He is a little more dour so the Australian style will actually help him a little bit we think," he said.
However the development of the horse will decide whether he targets staying or middle distance races.
"You just never know how they change, as we've seen with so many of these European horses," Henderson said.
"But you'd have to think that the aim for him would be the Sydney Cup."
Geelong Cup winner Gatewood is in the spelling paddock and will be sent to champion Sydney trainer Chris Waller to continue his career.
