Tupou grew up in Canberra, playing both rugby league and rugby union during his youth though, so a deal from the nation's capital could talk.
The deal would lock Tupou in at Concord until at least the end of the 2026 season where he would have hoped to have properly cemented himself into first-grade by that time.
The 21-year-old, who was born in Auckland, has impressed during his time in first-grade, having debuted for the Tigers in 2022. He has gone on to play 26 first-grade times and be a rapid improver for the club.
Raised in Canberra, Tupou made the switch to the Tigers ahead of his first-grade debut, and his youthful age fits in with the club's recent mantra - the Tigers have made no secret of the fact they want to become known as a development club.
The report suggests Tupou has a strong relationship with new head coach Benji Marshall which could seal the deal, although no decision is expected before he returns from England, with the winger currently on tour with Tonga.
