CATHERINE KIRWAN

Lifestyle & Fitness Creator

Catherine Kirwan proves that age is irrelevant and that it’s more about how you carry yourself, how you live, and how you say yes to what excites you that makes the difference, especially when it comes to content creation.

For years, she’s channelled her eye for beauty into interiors, designing and styling for some of Australia’s most iconic names, including Freedom and Coco Republic. But Catherine’s influence doesn’t stop at design. At 57, (yes, seriously!) she’s redefining what it looks like to embrace health, fashion, travel and possibility with the kind of energy that makes her audience think, I want what she’s having.

Her turning point came at 55, when she entered a bodybuilding competition. Already accomplished in her career and confident in herself, Catherine wanted a new challenge. Training, stepping on stage, pushing her body to its limit. It was less about winning trophies and more about proving to herself that if she decided to do something, it would happen. That same determination now shapes the way she shows up online.

Catherine’s feed is a mix of feminine, coastal-inspired fashion, active living, and plenty of activewear, as well as family moments and travel snippets that inspire her audience to make room for new experiences. It’s not just about fabulous bikini shots and sun-kissed moments, it’s about health, confidence and the kind of energy that comes from showing up for yourself, day after day. Her content tells a bigger story: that setting goals, saying yes to adventures, and prioritising wellbeing are the real markers of style. And Catherine radiates it. You can’t fake that kind of vitality, and it’s why her audience doesn’t just scroll, they stop, they save, they lean in.

For brands, Catherine represents more than reach. She embodies a mindset that’s underrepresented yet powerful: that life doesn’t slow down after a certain age - it expands. Her content reminds her audience, whether they’re 40, 50, or beyond, that possibility doesn’t come with an expiry date.

Set to appear in Australia’s first-ever series of The Golden Bachelor in late 2025, Catherine is proof that with the right mindset, life doesn’t have to slow down after a certain age. It can open up in ways you never imagined.
