The yellow team on The Block 2026 is the season’s biggest question mark. Channel Nine has deliberately kept West Australians Rosco Wilson and Lisa Dunbar under wraps, calling them “perhaps the most mysterious couple joining the season.”
Update (9 July 2026): Nine’s official trailer confirms Rosco and Lisa as the yellow team, rounding out a cast drawn from four states. See all five teams in our team colours breakdown.
Who are Rosco and Lisa?
The pair are from Western Australia, secondary reporting places them as Rosco Wilson and Lisa Dunbar, though Nine has released far less detail on this team than the other four so far. That kind of deliberate mystery is often a producers’ tell that a team has a strong story to hold back for the premiere itself.
What to expect
With almost nothing officially confirmed beyond their state and team colour, Rosco and Lisa are the team to watch for a big reveal once the season proper begins. We’ll update this profile in full as soon as Channel Nine publishes official cast bios or the premiere airs.
The Block 2026 premieres Sunday 2 August on Channel Nine and 9Now, confirmed in the official trailer released on 9 July. Full team profiles are on our The Block 2026 hub.
Note: names, team colour and the quoted details above are drawn from Nine’s official trailer and cast introduction. Some background details are drawn from secondary reporting and remain unconfirmed until Nine publishes official cast bios closer to the premiere. We’ll update this post when they land.
