Some of The Block 2027 (Season 23) is now official, but the internet keeps guessing at the rest. This page is the running ledger of everything claimed, reported, leaked or guessed about it, with every entry rated for confidence. Nothing gets quietly deleted: when a rumour dies, it gets marked Busted and stays on the board as a monument to whoever started it. Bookmark it, because this is where every scrap of 2027 news will land first, including any movement on casting and applications and the Sunbury site.
How to Read This Page
Every claim carries one of five statuses, so you always know how much weight to put on it:
- Speculation: Our own analysis, with the methodology stated. Nobody has reported this; we are reading patterns and saying so out loud.
- Rumour: One outlet has reported it. Treated as unconfirmed.
- Corroborated: Two or more independent outlets are reporting the same thing.
- Confirmed: Channel Nine or an official source has said it. It then graduates off this page and into the main 2027 page.
- Busted: Contradicted by an official source. Stays visible, with a note.
Speculation entries also carry a hi-vis confidence rating: one vest is pub talk, two vests is a pattern worth respecting, three vests is close enough to certain that we have started drafting the recap.
Location Claims
| Claim | Status | Our read |
|---|---|---|
| The Block 2027 will be filmed in Sunbury, at the heritage-listed Jacksons Hill site (formerly Caloola) | Confirmed | Scott Cam and Shelley Craft named it at Nine’s 2027 Upfront on 17 September. Three heritage buildings on the site of the former Sunbury Asylum. Suburban fences after Mount Eliza’s water view is the vibe shift we called. Full breakdown on our Sunbury explainer. |
| The Block 2027 will be in Victoria | Confirmed (was Speculation, three vests) | Every season since 2012. The show would sooner replace Scotty than leave Victoria. |
| Three heritage buildings become five homes for five teams | Corroborated | realestate.com.au, the Herald Sun, Domain and Australian House and Garden all report it. Nine has not released a floor plan or explained how three buildings become five homes. |
| Nine chases another coastal or water-view site if Mount Eliza pays off at auction | Busted | Sunbury is not coastal. Logged here so you can grade us on it. |
| Permit plans show five competition homes with pools and glass living pavilions, plus a smaller sixth home for The House Next Door | Corroborated | The competition homes run from roughly 518 to 615 square metres, so nobody is getting a shoebox. The sixth house swaps a pool for a spa, which feels very spin-off budget. |
| House 3’s rear addition requires demolishing a 1935 former hospital dining room | Rumour | One outlet reading the permit papers. If it holds, heritage advocates will have their own reveal night. |
| Hume City Council has formally raised concerns with the state government about the site going into private hands | Rumour | The Block has survived cranky neighbours before, but a council on the record is a different beast. Watch this before the permit decision lands. |
Timing and Format Claims
| Claim | Status | Our read |
|---|---|---|
| The Block 2027 premieres in late July or early August 2027 | Speculation (two vests) | Still the safest bet on the page, but downgraded a vest because Nine needs Heritage Victoria approval before works start. |
| Casting for 2027 opens during the 2026 broadcast season | Confirmed | Nine has officially opened casting for season 23, with applications running Australia wide ahead of a 12 week shoot from February 2027. See how to apply. |
| Nine’s 2027 Upfront was held on Thursday 17 September 2026 at The Cutaway, Barangaroo | Confirmed | This is where the Sunbury location was revealed, as predicted. Follow along with #NineUpfront. |
| A secret sixth house gets its own All Stars spin-off, “The House Next Door,” exclusive to Stan | Confirmed | Announced alongside the location at the same Upfront. Fan-favourite former Blockheads renovate a sixth property over the fence on the Jacksons Hill site, with weekly reveals shown only on Stan. Contestants, judges and a premiere date are not yet confirmed. |
| The heritage permit for Jacksons Hill goes out for public comment | Corroborated | Heritage Victoria has opened submissions and the window is short. Our Sunbury breakdown has what the plans show. Speak now or forever hold your pressed metal ceilings. |
Cast and Judges Claims
| Claim | Status | Our read |
|---|---|---|
| Scott Cam and Shelley Craft return as hosts | Confirmed | Both named the Sunbury location at the Upfront, and both host The House Next Door on Stan. |
| Darren Palmer, Shaynna Blaze and Marty Fox return as judges | Speculation (one vest) | The Herald Sun understands none of the current panel has been confirmed for 2027 yet, so this drops from two vests to one. |
What We Are Watching
Leaks rarely start with a press release. They start with paperwork. Our scan watches, in rough order of usefulness: council and heritage planning registers, property purchase reporting from Domain and realestate.com.au, the official MyCastingNet casting page, Nine’s announcements, trade press (TV Tonight, TV Blackbox, Mediaweek), and the gossip weeklies (New Idea, Woman’s Day, WHO), reported here with attribution and an appropriate level of scepticism.
The Rules We Hold Ourselves To
Every claim is checked against a named source before it goes on the board. Predictions are labelled as ours, with the reasoning shown. Busted entries stay on the board. Claims about people are limited to casting and career reporting: no relationship or health gossip, ever. And when Nine confirms something, this page, the main 2027 page and the season hub all update the same day.
