Ten Sovereigns has put himself in the mix for the $14 million Everest in Sydney with his win in the July Cup at Newmarket.
The Coolmore-owned colt emulated stablemate U S Navy Flag who won the showcase sprint last year.
U S Navy Flag travelled to Australia for the 2018 Everest but struck an unsuitable wet track and was unplaced.
A 9-2 chance on Saturday (Sunday AEST), Ten Sovereigns gave trainer Aidan O'Brien a record-equalling fifth July Cup when he beat Advertise by 2-3/4 lengths.
Coolmore Australia boss Tom Magnier said Ten Sovereigns would be considered for the operation's slot in the world's richest turf race race at Randwick on October 19.
“Obviously he was very impressive last night,” Magnier told Sky Sports Radio.
“We don't have to make a decision just yet. We've got horses here like Yes Yes Yes with Chris Waller but we'll put Ten Sovereigns into the mix.
“We are not close to a decision but we will put him on the radar now.
“To be fair to my father (John Magnier) this is where we want to race. The prize money and the vibe around these races is second to none.
“And that's why we are bringing Justify and American Pharoah here.”
The past two American triple crown winners are in quarantine and will travel to Australia in about two weeks to prepare for the southern hemisphere breeding season.
Magnier confirmed Saturday's Winter Stakes winner Eckstein would have one more run in the Winter Challenge before she is retired.
She was bought purposely at the recent National Broodmare Sale to be mated with Justify.
