Tom Trbojevic has scored seven tries for Australia at the World Cup, tying him for the tournament lead.
Despite being eligible to negotiate with rival NRL clubs for 2028, the 30-year-old has received a two-year contract offer from Manly, the Sydney Morning Herald reports.
Trbojevic has previously shown loyalty to the Sea Eagles, even offering to take a pay cut before the NRL intervened.
Soft tissue injuries disrupted his 2026 season, forcing Manly to use other fullbacks, but the article notes his quality when fit.
The club has also offered Lehi Hopoate a two-year extension, with the 21-year-old currently off contract at the end of 2027.
Hopoate is Tonga's first-choice fullback at the World Cup and has demonstrated his potential for the role, while other clubs could be interested if he tests the market.
Fijian international Caleb Navale is reportedly in advanced talks to stay at Manly after making only a handful of NRL appearances between 2024 and 2026.
His ball-playing and powerful leg drive have impressed at lock, where he could eventually follow Jake Trbojevic, who has held the position for a decade.
Retaining all three would be a significant result for coach Kieran Foran as he shapes the squad during his first full season in charge.
