Newcastle fullback Connor Votano will move to Belmore after an impressive 2026 NSW Cup campaign.
The 20-year-old played 17 matches, scored seven tries, averaged 127 metres and recorded 15 try assists, while kicking 56 goals.
Canterbury-Bankstown's general manager of football confirmed four players would join for 2027, with Phil Gould announcing the news on social media Friday.
Penrith hooker Freddy Lussick headlines the group, and reports say he has agreed to a two-year deal.
He has played for the Roosters, Warriors and Panthers, but has not secured a regular starting role; he also made two appearances for the Dragons on loan.
The Bulldogs offer Lussick his biggest opportunity yet, with his sharp service and deceptive running game seen as qualities the club has lacked in recent seasons.
Penrith outside back Jesse McLean is also joining after limited NRL opportunities.
Older brother of Kiwis star Casey, Jesse has made four NRL appearances since his 2023 debut.
He co-captained the Australian Schoolboys in 2022 and scored a match-winning double in the SG Ball Grand Final.
McLean later co-captained the Under-19s NSW Blues alongside Casey in their successful 2024 representative campaign.
He will add outside-back depth for Cameron Ciraldo after Bronson Xerri's departure.
