The toolkit never sat still
Home-cook competitions don't usually redesign their own machinery this often — a new advantage mechanic most years, the judging panel growing from three chairs to four, mentors and finale formats quietly rewritten underneath. This tracks all seventeen seasons by what got rebuilt, not by who won.

The 17, in order.
- #01
A new three-judge panel and an all-returnee cast rebuild the format the same year.
Three brand-new judges meet a cast of former high-achievers, and the weekly rotation gets redesigned start to finish — Mystery Box, Team Challenge, Pressure Test, Immunity, elimination — into a shape the founding era never locked in. - #02
The founding era's first recurring strategic advantage enters the competition.
Season six brings the audition stages back and introduces the Power Apron, an advantage that follows its holder across multiple challenges instead of resolving in a single episode — the format's first deliberate structural wrinkle in years. - #03
The panel grows from three chairs to four for the first time in the show's history.
Andy Allen is joined by three new judges at once, the biggest change to the panel's shape since the founding trio departed. Three episodes shot in Hong Kong give the expanded panel its most distinctive stretch to work with. - #04
Two separate advantage mechanics merge into one hybrid apron for the milestone season.
The Ten-Year Superpower apron folds the immunity and Power Apron privileges built up over prior seasons into a single object, the format's most complex strategic mechanic yet, timed to the season that also brings Gordon Ramsay in for the first time. - #05
A new timed advantage debuts the same season the format leaves Australia for Asia.
The Power Pin banks its holder fifteen extra minutes in any future challenge through the finals, a strategic layer introduced alongside the founding era's most ambitious location week, filmed across Tokyo's restaurants and markets. - #06
MasterClasses disappear and a concealed-identity apron replaces the usual open advantage.
Season fifteen drops the MasterClass format entirely and introduces a secret apron whose holder stays hidden from the rest of the field, plus blind-tasting immunity rounds judged without knowing who cooked what. - #07
The all-returnee premise repeats, this time against a panel that already knows itself.
Six years after season twelve introduced it, the Back to Win format returns with twenty-four contestants spanning the show's full history. What changes isn't the cast structure — it's a four-judge panel meeting it settled instead of new. - #08
The cast splits into two competing groups for the first time, then merges mid-run.
Twelve new Fans and twelve returning Favourites run separate tracks for six weeks before merging into one field, a structural first for the format's cast makeup, staged partly on location in Tasmania. - #09
The competition leaves Australian soil for the first time in the format's run.
The penultimate week relocates the remaining field to San Francisco, Napa Valley, and San Diego — the founding era's first international travel, paired with expanded restaurant-service challenges back home. - #10
A brand-new panel meets a brand-new cast, with the season's advantages capped upfront.
Three Immunity Pins, all allocated in the opening Mystery Box, are the season's entire strategic currency — a tighter, more limited advantage structure than the mechanics the founding era kept adding to. - #11
The grand finale grows from two finalists to three for the founding trio's last run.
Three former contestants take over the mentor role, and the finale expands to three finalists instead of the format's usual two — a late structural change arriving the same season the founding panel closes out its run. - #12
The format tests whether a much longer season can still hold together.
Season two extends the episode count well past the debut's run, the first real test of whether the competition's structure can sustain a full-length season rather than an introductory one. - #13
The Power Apron format settles, and the recurring mentor role changes hands.
Shannon Bennett takes over as recurring Immunity mentor from Kylie Kwong, and a returning guest chef anchors a second consecutive dedicated week — the format running its year-old mechanic with more confidence, not a new one. - #14
The format finds a settled rhythm without adding a single new mechanic.
No new advantage, no panel change, no relocation — season three's whole swing is internal, the audition circuit and elimination structure finally running with the confidence the first two seasons were still building toward. - #15
The season with nothing yet built to swing away from.
No Australian template existed before this one — a three-judge panel and a nationwide audition search invent the format's grammar in real time, rough edges and all, before there's anything established yet to rewrite. - #16
A recurring guest's own challenges become a structural fixture, not a one-off.
A recurring celebrity chef's appearances stop functioning as a single guest slot and start operating as a creative force across the whole season, setting a template for how later seasons would build entire weeks around one distinctive cook. - #17
The one founding-era season that changes nothing on purpose.
No new advantage, no panel shake-up, no relocation — season five is the format running its established template at full confidence, the control case against every season around it that reached for a structural swing instead.
