Events over the next 10 days will determine whether Nigel Tiley will be back in Melbourne in the spring.
The Pukekohe Park trainer is currently putting the finishing touches on Megablast, who will make his Australian debut at Moonee Valley today in the hands of Ben Melham.
"It's a learning curve and we're here to see how he copes with the travel and to this point he has coped very well," Tiley said.
"He's travelled nicely and he enjoyed a working gallop with one of Trent Busuttin's horses this morning at Cranbourne.
"We want to see where he sits over here and if he happened to be dominant then we would be looking at bringing him back over in the spring."
