Jack Bostock scored three tries in the 66-6 win over the Cook Islands on Saturday night.
The Dolphins centre has lost only once since returning from a 2025 ACL injury: the preliminary-final loss to the Sydney Roosters, who went on to win the title.
His form has made him one of the off-season's leading free agents, with Sydney clubs linked to him and speculation he could leave the Dolphins after 2027.
"I spoke to the Dolphins a couple of weeks ago and said I wanted to see my options and what I could do."
"It's not set in stone I'm leaving the Dolphins. It's a matter of going through the process.
"It's hard to do while you're in here because the task at hand is winning the World Cup."
"Once I can sort out a time with my manager, we'll sit down during the week, or have a phone call, and start figuring out what we're going to do.
"We can see how many players are coming off on November 1. It's been a running joke in camp about who is going where and what's going to happen."
The 23-year-old Illawarra junior has friends and family in the area, but has said those ties will not decide his future. He has also previously said he would like to stay at the Dolphins under coach Kristian Woolf.
The Dolphins reached the preliminary finals in their first finals campaign, before losing to the eventual premiers.
