If you’ve spent any time on Netflix lately, you know the Miller family is basically the definition of "it’s complicated." But while Ginny and Georgia trade verbal barbs and cover up literal crimes, there’s one character who usually stays in the shadows until he absolutely has to step into the light. I’m talking about Austin Miller. Specifically, the ginny and georgia austin actor, Diesel La Torraca.
Honestly, it’s kind of wild to watch him on screen. One minute he’s this adorable kid in Harry Potter glasses, and the next, he’s witnessing a murder or shooting his own father in the arm. It’s a lot for a kid. Even more so when you realize the actor behind the character has been growing up in real-time while the show’s timeline stays stuck in a permanent Wellsbury winter.
Who is the Ginny and Georgia Austin Actor?
So, let's get the basics out of the way. The ginny and georgia austin actor is Diesel La Torraca. He was born on March 1, 2011. If you’re doing the math, that makes him a full-blown teenager now.
He’s Australian, which usually shocks people because his American accent is pretty much flawless. He was raised in Collaroy, part of Sydney’s Northern Beaches. Acting is kinda in his blood; his mom, Joanne Hunt, is an actress too. You might have seen her in Home and Away.
Diesel started out in commercials when he was just five. By the time he landed the role of Austin, he was already a veteran of sorts. He’d done Little Monsters with Lupita Nyong’o—which, if you haven’t seen it, is a zombie comedy that is way better than it has any right to be.
The Growth Spurt Everyone is Talking About
Here’s where things get weird. Production cycles for Netflix shows are notoriously long. Season 3 of Ginny & Georgia didn't hit screens until June 2025. Because of the strikes and typical streaming delays, years passed between filming sessions.
In the show? Austin is still supposed to be around nine or ten years old. In real life? Diesel La Torraca is 14.
He’s taller than Antonia Gentry (who plays Ginny) now. It’s become a bit of a meme on TikTok. Diesel even posted a video joking about "trying to convince people Austin is still 9." In an interview with Teen Vogue, he admitted they’ve had to use some old-school movie magic to hide his height. Sometimes he has to slouch or bend his knees in shots. Sometimes the crew puts Antonia on an "apple box" to make her look taller.
It’s the Stranger Things effect all over again. You can't stop puberty, even if your character is stuck in a narrative loop.
More Than Just the "Quiet Kid"
People underestimate Austin. In the first season, he was mostly the target of bullies and the recipient of Georgia’s "creative" parenting—like when she taught him how to stab a kid with a pencil. But as the show has progressed, the ginny and georgia austin actor has had to go to some really dark places.
Think about Austin’s trajectory:
- He finds out his dad is a convict.
- He realizes his mom has been forging letters from said dad.
- He watches his mom smother Tom Fuller with a pillow.
- He shoots his biological father, Gil, to protect Georgia.
That’s a heavy load for a child actor. Diesel has mentioned in interviews that playing Austin is a challenge because he has to tap into a "shy, insecure" energy that he’s personally outgrown. He has to consciously heighten his voice register because his voice has naturally deepened. It’s a technical performance that most people don't give him enough credit for.
Life Outside of Wellsbury
When he’s not dealing with the chaos of the Miller household, Diesel is a regular kid—well, as regular as a Netflix star can be. He splits his time between Sydney and Los Angeles. He’s big into basketball. You’ll often see him posting about it on Instagram.
He’s also building a pretty impressive resume outside of the show.
- IT: Welcome to Derry: He’s part of the prequel series for Stephen King's IT.
- Unsung Hero: He played Joel Smallbone in this 2024 film.
- La Brea: He had a recurring role as Isaiah.
He’s not just "the kid from Ginny and Georgia" anymore. He’s becoming a sought-after talent in both Australia and the US.
Why Austin Matters for Season 4 and Beyond
With Season 3 having ended on such a massive cliffhanger—Georgia being arrested at her own wedding—Austin is in a precarious spot. He’s the only one who actually saw what happened to Tom. That secret is eating him alive.
The ginny and georgia austin actor has teased that Austin’s relationship with Ginny is changing. They’ve gone from typical siblings to trauma-bonded allies. Austin used to be the "run of the litter," but now he’s the one holding the most dangerous information in the family.
Fans have some wild theories. Some think Austin is going to turn into a "mini-Gil," reflecting the violence he’s been exposed to. Others hope he’ll be the one to finally break the cycle of lies. Whatever happens, Diesel La Torraca has the range to pull it off. He’s moved past the cute kid phase and into a space where he can handle the gritty, psychological stuff the showrunners love to throw at the Millers.
What’s Next?
If you want to keep up with Diesel, his social media is the best bet. He’s very active and seems to genuinely enjoy the fan interaction. He often shares behind-the-scenes clips with the cast, especially with Felix Mallard (Marcus) and Scott Porter (Paul).
As for Ginny & Georgia, the show has already been renewed for Season 4. We’re likely looking at another long wait, which means by the time we see Austin again, he might be towering over the entire cast. But honestly? We’re here for it. Watching this kid grow up—both as a person and an actor—has been one of the most interesting parts of the series.
Actionable Insights for Fans
- Watch his early work: Check out Little Monsters on Hulu or Lambs of God to see Diesel's range before he became Austin Miller.
- Follow the BTS: If you’re worried about the dark themes of the show, Diesel’s TikTok often shows the lighthearted side of filming, which is a nice palate cleanser.
- Prepare for a time jump: Given the "aging" issue, don't be surprised if Season 4 includes a significant time jump to align the characters' ages with the actors' real-life growth.
Diesel La Torraca is proof that child actors can navigate the transition to teen roles without losing their spark. He’s arguably the most grounded part of a show that is frequently unhinged, and that’s no small feat.
