A late Perth Cup nomination for Cantonese will remain on hold until travel plans for the in-form Sydney stayer are confirmed.
Cantonese was expected to be sent to Melbourne by road on Tuesday to wait for a flight to Perth on Friday.
West Australian racing officials are confident - with minor reservations - Cantonese will take his place in the January 1 race.
"Cantonese is an eighty per cent chance of getting a flight," Perth Racing's Marty Young told AAP.
"But, if for some reason the flight doesn't go, then the horse won't be coming across because there won't be another one to get him here in time."
Connections have until Monday to lodge a Perth Cup late entry for the stayer who has won six of nine starts since he was sold to clients of trainer-on-the-move Bjorn Baker.
Baker confirmed he would like to run Cantonese in the Perth Cup, instead of setting last Saturday's Rosehill Listed Christmas Cup winner for the Auckland Cup.
Providing there are no travel hitches, Cantonese will join Shamardashing, the Patinack Farm-owned stayer already campaigning in Perth, as the only two eastern states runners in the Cup.
"The plan now is to go to Perth if the logistics allow," Baker said.
Jim Cassidy, who rode Cantonese for the first time in the Christmas Cup on Saturday, will keep the ride in the $500,000 race for which the five-year-old will be weighted on the 53kg minimum.
"If the flights don't work out I'll more than likely bring him back to Sydney for the Summer Cup (on Boxing Day)," Baker said.
Cantonese is pressing for Cup favouritism in an updated TAB pre-post market at $5.50 behind Chester Road ($5).
Chester Road already represents a liability of more than $350,000 for the TAB after being coupled in a double with last Saturday's Flemington winner Lampedusa.
Cantonese spent time in a paddock after giving Baker a breakthrough stakes victory with his six-length Christmas Cup win.
"He's got to come to the end of the line sooner or later but he's showing no signs that he's had enough," Baker said.
Baker, who has built his stable numbers to 30, will produce two first starters - Snippetson colt Fuerza and Testa Rossa filly Twilight Royale - in the $250,000 Inglis Nursery Stakes at Warwick Farm on Saturday.
"It was up for some debate about whether they should run but that has been taken out of my hands," Baker said.
"Commonsense dictates they have to run because it's a quarter of a million-dollar race on their home track."
