Adult Swim is known for greenlighting shows that feel like a fever dream you had after eating too much cheese at 3 AM. YOLO: Crystal Fantasy fits that description perfectly. It’s loud. It's weird. It’s distinctly Australian. Created by Michael Cusack—the same chaotic mind behind Bushworld Adventures and Smiling Friends—the show follows two best friends, Sarah and Rachel, as they navigate the surreal landscapes of Wollongong. But when people look up the cast of YOLO: Crystal Fantasy, they often expect a massive ensemble of Hollywood names.
The reality? It’s a tight-knit group of voice actors and comedians who basically built this world out of thin air and sheer Australian audacity.
The Core Duo: Sarah and Rachel
At the heart of every episode are Sarah and Rachel. Their dynamic is essentially the "straight man" versus the "agent of chaos," though in this show, even the straight man is pretty unhinged.
Sarah is voiced by Sarah Bishop. Bishop isn't just a voice actor; she's a powerhouse in the Australian comedy scene. You might recognize her from the comedy trio Skit Box, which went viral years ago with the "Activewear" video. Her portrayal of Sarah is grounded, or at least as grounded as you can be when your best friend is trying to find a party in a literal hellscape. Bishop brings a specific kind of "exhausted millennial" energy to the role that makes the surrealism feel weirdly relatable.
Then there’s Todor Manojlovic as Rachel. If you’ve ever met that one person who refuses to let a night end even when the sun is coming up and everyone is crying, that’s Rachel. Manojlovic captures that manic, self-destructive, but somehow endearing spirit perfectly. Interestingly, Manojlovic has worked with Cusack on several projects, and their chemistry—even through the medium of animation—is palpable. He doesn't just read lines; he screams them with a sincerity that makes you believe Rachel really would do anything for a "mazzo" night out.
Michael Cusack: The Man of a Thousand (Weird) Voices
You can't talk about the cast of YOLO: Crystal Fantasy without mentioning Michael Cusack himself. Much like Justin Roiland did with Rick and Morty or Trey Parker and Matt Stone do with South Park, Cusack voices a massive chunk of the supporting cast.

He’s the voice of Lucas the Magnificent. He’s various bush wizards. He’s the random creatures that inhabit the background of Wollongong. Cusack’s voice acting is characterized by a specific kind of stuttering, improvisational feel. It feels raw. It feels like he’s making it up as he goes, which adds to the show's lo-fi, DIY aesthetic.
Cusack’s influence on the show goes beyond just the voices. He is the architect of this entire universe. His style—often referred to as "Aussie Shitposting" turned into high art—relies heavily on the vocal performances being as ugly and honest as the character designs. There’s no ego here. The voices aren't meant to be "pretty." They’re meant to be loud, grating, and hilarious.
Supporting Players and Recurring Weirdos
The world of YOLO: Crystal Fantasy is populated by a revolving door of bizarre entities.
- Greig Pickhaver: Better known to Australians as H.G. Nelson from the iconic sports comedy duo Roy and HG, Pickhaver provides his legendary pipes to the show. Seeing a veteran of Australian broadcasting join a show about crystal-obsessed party girls is a testament to how much respect Cusack has earned in the industry.
- Michelle Brasier: A staple of the Melbourne comedy circuit and a frequent collaborator with the Aunty Donna crew, Brasier brings a sharp comedic timing to various guest roles.
- Brendan Williams: Another frequent flyer in the Cusack-verse, Williams helps fill out the world with voices that feel authentically "Wollongong."
The show also features a variety of guest spots that pop up and disappear before you can even check IMDb. It’s a "who's who" of the Australian underground comedy scene, rather than a list of A-list celebrities. And honestly? That's why it works. If you put Chris Pratt in this show, the illusion would shatter instantly.
Why the Voice Acting Style Matters
The cast of YOLO: Crystal Fantasy doesn't follow the traditional rules of animation. In many big-budget shows, actors record their lines in isolated, soundproof booths with a director meticulously polishing every syllable.

Cusack’s approach is different. It feels collaborative and loose. There’s a lot of "mucking around" that makes it into the final cut. You can hear the actors almost breaking character, or the natural stumbles of someone actually trying to hold a conversation. This is a deliberate choice. It mimics the chaotic energy of the animation itself. The "Crystal Fantasy" isn't supposed to be polished. It’s supposed to be a reflection of the messy, confusing, and often gross experience of being young and aimless.
Misconceptions About the Cast
One thing that surprises people is that the show isn't entirely improvised. While it sounds like a bunch of friends just riffing over some drawings, there is a tight script at the core. Sarah Bishop has mentioned in interviews that while there is room for "flavor," the emotional beats between Sarah and Rachel are carefully written.
Another common misconception is that the show is "just" for Australians. While the accents are thick and the slang is specific (good luck explaining a "shoey" to someone who hasn't seen it), the cast performs with a universal energy. The themes of friendship, FOMO, and the desire to find something "magical" in a boring town resonate everywhere. The cast manages to translate specific Australian "feral" energy into something globally understood.
The Evolution into YOLO: Silver Destiny
When the show returned for its second season, rebranded as YOLO: Silver Destiny, the core cast remained the same, but the stakes got... weirder? If that's even possible. The chemistry between Bishop and Manojlovic deepened. We saw more of Sarah’s internal struggle and Rachel’s bizarre quest for "destiny."
The voice acting in the second season felt more confident. The actors knew these characters inside out. They weren't just finding the voices anymore; they were inhabiting them. This evolution is key to why the show has maintained a cult following. It’s not just a series of random gags; it’s a character study of two very flawed, very loud women.

Behind the Scenes: The Recording Process
Recording for a show like this usually happens in small studios in Melbourne or Sydney. Because the show is produced by Princess Bento Studio (a collaboration between Melbourne’s Princess Pictures and US-based Bento Box), there is a bridge between Australian talent and American distribution.
The actors often talk about the physicality of the roles. You can’t voice a character like Rachel while sitting still. It requires energy. It requires waving your arms around and actually feeling the frustration or excitement of the scene. That physical energy translates into the audio, giving the show its signature high-octane feel.
How to Follow the Cast Further
If you’ve fallen in love with the voices behind the madness, the best thing you can do is look into the Australian comedy scene.
- Check out Skit Box: To see Sarah Bishop’s live-action work. It’s brilliant, sharp, and gives you a better appreciation for her range.
- Follow Michael Cusack on YouTube: His early animations are where many of these voices were born. You can see the DNA of YOLO in his older sketches.
- Watch Aunty Donna's Big Ol' House of Fun: Many of the guest voices and collaborators on YOLO move in the same circles as the Aunty Donna guys.
- Listen to Australian Comedy Podcasts: Many cast members appear on shows like Dragon Friends or various Melbourne International Comedy Festival specials.
The cast of YOLO: Crystal Fantasy represents a specific moment in animation where the "fringe" became the "mainstream" (at least on Adult Swim). They proved that you don't need a cast of movie stars to create something that sticks in people's brains. You just need a few talented people, a microphone, and a very strange vision of what happens on a night out in Wollongong.
Actionable Insights for Fans
To truly appreciate the work of this cast, watch an episode with headphones on. Pay attention to the background chatter and the "non-scripted" sounds—the sighs, the half-laughs, and the way the voices crack. It’s in those imperfections that the real magic of the show lives. If you’re an aspiring voice actor, notice how Cusack and his team prioritize character over clarity. Sometimes, being "perfect" is the least interesting thing you can be.
Next time you’re watching Sarah and Rachel argue over a magic kelpie or a party invite, remember that it’s just a small group of Australians in a booth, probably laughing just as hard as you are. That’s the real crystal fantasy.
