Jason Warren has witnessed the success other Australian trainers have had with European imports and thought it was about time he tried his luck as well.

At Sandown on Wednesday, Warren will saddle up four-year-old mare Suspicieuse who was bought from France in December and makes her Australian debut in a 1600-metre benchmark race.

Warren has raced an import before but that horse had come to him from an Australian trainer and he said this was different because it was the first horse sent straight from northern hemisphere to his stable.

"It's the first international horse that I have bought, so hopefully it works out all right," Warren said.

"(Bloodstock agent) Sheamus Mills bought her for us for the clients.

"We contracted Sheamus to find an import for us and he found her over there at a sale at Deauville."

Suspicieuse has won one of her nine starts - a maiden over 2000m in January last year - and was Listed-placed over 1600m last May.

The mare arrived at Warren's stable in January and the trainer is looking forward to her stepping out.

"She has settled in really well. She came out of minus four degrees into about 43 degrees over here in January so it was a big shock to her," he said.

"We just gave her a few weeks just to settle in and acclimatise and then we started working her up.

"We've been able to put a few trials into her and have her reasonably forward for tomorrow."

The daughter of Elusive City was fourth in a trial at Cranbourne last month and has also had a recent jump-out at Balnarring.

Daniel Stackhouse has the ride and Warren expects the mare to run well.

He said he would be guided by her initial Melbourne starts before making long-term plans.

"Sometimes they take a bit of racing to settle in," he said.

"She's settled in very well in the stable, but it doesn't mean she's used to our way of racing yet.

"Ideally we'll give her a couple of runs now and get her rating up a little bit and then we can hopefully look for better races with her."
