Round two: Go Wild!

A tweenager from the US who's just landed in Fiji to live with her grandmother and cousins. She's lost, a little sad, and genuinely isolated under a brave face — being a foreigner with a hearing aid isn't exactly the fast track to popularity, and her cousins have already nicknamed her "Rachelli."

When she discovers she can talk to Saboo, everything changes, and she becomes the one who rallies humans and sea creatures alike.

We need real range here: comedy, vulnerability, and a growing confidence that builds across the series as she finds her family and her place.

Self-appointed caretaker of the reef. Maternal without being soft, protective without being smothering — she's watched this reef for decades and won't let it disappear without a fight. When a plastic bag nearly costs her her life, her patience finally runs out and she finds her purpose.

She becomes the translator and emotional anchor between the ocean crew and Rachel, the reason this unlikely team becomes more than the sum of its parts. Underneath the wisdom, there's real teenager energy.

Trained herself through sheer stubbornness to glide 180 metres in a single leap. Thinks in military shorthand: "Roger that." "Copy." A foot soldier who finally finds her mission and her people here. Totally certain about the chain of command, though she never quite agrees with anyone about who's actually in charge.

She's the one scouting from above the waterline, clipped, energetic, mock-serious, always reporting in.

An uber-billionaire building a floating retreat off the coast. She's aware of climate change but has decided to survive it rather than fight it, creating a sanctuary for people like her regardless of how high the seas rise. Narcissistic and self-centred to her core — in her mind there's only one way, and it's hers.

She solves every problem with money and turns on people in an instant, completely for you one moment, completely against you the next. Not exactly evil, but selfish and morally out of whack.

Glossy, commanding, and a little terrifying.

Rachel's grandmother, taking her in as she adjusts to a culture and family she doesn't yet understand. Maternal, gentle and sweet, the warm, steady presence at the centre of the family — family, to Bubu, is not just the people who share your blood.

We had very few auditions for Bubu in round one, so if you can bring that Islander warmth, we especially want to hear from you.

Rachel's one friend on the island. Builds the device that amplifies her cochlear implant, unlocking her ability to speak with Saboo. Tech-minded, loyal, quietly brave, and genuinely delighted by everything — think Labrador puppy energy, a little too chatty, entirely sincere.

He didn't build the device to talk to fish; he built it so Rachel would stop feeling like nobody could hear her.

Fifteen centimetres tall and convinced he's ten feet tall. Full Napoleon energy — small man syndrome in a huge way.

Carries a deep, unshakeable conviction that humans are the problem; he's collected the evidence personally, and the ocean is full of human debris he's encountered first-hand.

Scrappy, loud, desperate to prove himself despite his size, and he's been Saboo's closest friend since long before this story started.

A prankster and trickster who changes colour and personality as often as the moment demands — jokester, fighter, stand-up comic, mopey teen, whatever the scene needs.

Can squeeze into impossibly small spaces, can regrow a lost arm, and genuinely can't take anything seriously until it's absolutely critical. Then he's exactly what the team needs.

We're genuinely open on interpretation here, so bring us your take.

Former Chief Engineer for the Thorne Corporation, now a passionate, frizzy-haired climate activist nobody takes seriously.

He'll protest, chain himself to trees, do whatever it takes to get the message out — genuine, pushed right to the edge, and entirely correct that if people could only hear the fish, they'd change their minds.

The team's unlikely hero in the final act.

Obsequious and more than a little cunning, entirely devoted to Miriam and her plans — for now.

Where his loyalties end up later in the season is still an open question.

We'll shortlist from these tapes, then bring our favourites together in Sydney for an in-person chemistry audition and final casting session. This is a year-long collaboration and that in-person connection matters as much to us as the tape does.
