You know that feeling when you're re-watching a show from your childhood and you suddenly realize you have no idea what the actors are actually called? It happens every time I fall down an H2O: Just Add Water rabbit hole. We all spent years watching Lewis McCartney try to use "science" to explain why his friends turned into mermaids, but if you saw him on the street today, would you even know his name?
Angus McLaren is the man behind the vest and the fishing rod.
Honestly, he was the glue that held that chaotic Mako Island trio together. While Cleo, Emma, and Rikki were busy accidentally freezing people or causing indoor rainstorms, Lewis was the one person they could actually trust. He wasn't just a sidekick; he was their tech support, their secret-keeper, and eventually, the guy who won Cleo’s heart.
Who is Angus McLaren?
Born on November 3, 1988, in Leongatha, Australia, Angus grew up on a dairy farm. It’s a far cry from the sunny beaches of the Gold Coast where H2O was filmed. He didn't just stumble into acting, either. He was a professional from a young age, appearing in shows like Something in the Air and Worst Best Friends before he ever stepped foot in the JuiceNet Cafe.
He’s roughly 5'10" (around 1.79 meters), which made him the perfect height to play the slightly-awkward-but-charming Lewis.
One thing people often get wrong is thinking he just vanished after the show. He didn't. In fact, his departure from the series in Season 3—when Lewis went to "America" to study—was actually because Angus landed a massive role in another iconic Australian show.
Life After Mako Island
If you live in Australia, you probably know him better as Nathan Rafter.
Right as H2O was reaching its peak, Angus joined the cast of Packed to the Rafters. It was a huge deal. It’s one of the most beloved family dramas in Aussie history. He spent years on that show, proving he wasn't just "the kid from the mermaid show" but a serious actor with range.
He’s had a pretty eclectic career since then.
- The Doctor: He popped up in Doctor Doctor.
- The Big Screen: He was in the 2018 film Hotel Mumbai.
- The Music: He’s a drummer! He was in a band called Rapids for a while.
It’s kinda wild to think that while we were obsessed with whether Lewis and Cleo would end up together, Angus was busy building a massive career in the Australian TV industry. He even took some time off to study at the Western Australian Academy of Performing Arts (WAAPA) to sharpen his skills. That’s commitment.
Why Everyone Still Searches for Him
There is a weirdly specific nostalgia for Lewis. Maybe it's because he was the "nice guy" who actually stayed nice. He never tried to sell the girls out to the media, even though his scientific mind was probably dying to publish a paper on mermaid biology.
People search for lewis from h2o real name because they want to see what that lanky, blonde teenager looks like now. Spoiler: He aged well. He’s ditched the baggy 2000s shirts for a more rugged, mature look, but that smirk is still exactly the same.
What’s He Doing Now in 2026?
Angus has stayed relatively low-key compared to his co-stars like Phoebe Tonkin and Claire Holt, who went off to find massive fame in The Vampire Diaries. But low-key doesn't mean unsuccessful. He’s continued to work steadily in independent films and Australian television.
He's also stayed close with his former castmates. Every time a photo surfaces of the H2O crew together, the internet basically breaks. It’s comforting to know that the bond they had on screen wasn't just for the cameras.
If you’re looking to keep up with him today, your best bet is following his projects through Australian production news. He isn't the type to post 50 Instagram stories a day. He’s more of a "do the work and go home" kind of guy, which honestly makes him even cooler.
