Thanks to everyone who came to chat today and who visited our stall to snap up UnderSwim.

Swimming Australia Age Champs is always such a vibe and 2026 is absolutely no different.

Loving it even more this year because I have my girl, Poppy (aka Peanut aka Popstar aka My First Born), wingwomaning me. 👑💕

If you didn’t know we were there but you’re glad to find out we are and want to come and visit, we’re upstairs - next to Dr Hydrate.

Just our fave co-designer setting the media ablaze…. again. 🙌💕

Nothing could stop Kiera Austin from playing sport. But when she turned 14, Austin noticed a change. Fewer friends wanted to sign up for the next semester of sport and there was suddenly a “massive drop off” in participation.⁠

Now the Australian Diamonds netballer is taking action: https://tinyurl.com/5xyb74cc

Or the lucky one who gets a signed surprise 👀

Blink, and you’ll miss it.

Introducing… UnderSense 💫
They change colour depending on your mood.

Cranky? Different shade.
Delulu? Whole new palette.
Snacky, but nothing hits? Don’t even ask.

Honestly… no science behind it. Just vibes.

What she rates about UnderDance?
🩸 Makes period days easier
☁️ Seriously comfy
🩰 Hides under leos without the fuss
👌 Easy to wear, easy to trust

Not just endorsed. Co-designed.

Kiera set the standard. And not everything met it. If it didn’t hold up on court, it was out.

🎥 Watch to see what made the cut and why.

Activewear for Girls

For Girls Who Love To Move

We support tween and teen girls to live active lives and feel comfortable and supported doing it. However she loves to move, our four-way stretch fabric will move with her, our no-rub seams will prevent friction and our sweat-wicking properties will keep her cool and dry. And when she’s enjoying down time, Lava Tribe activewear gives her the chance to express her sporty style with fresh designs, bold prints and on-trend colours.

Our range is based on the basic principle that no matter what a girl sets out to achieve, if she feels comfortable and confident, she’s more than half way there.
