Powering Brand, Businesses,
& Ambition

Real strategy. No performance.

Established in 2018, Callista is a Melbourne-based boutique PR and content agency led by founder Mikhaela Delahunty.

Known for doing considered, transparent work — the kind that respects our clients, their businesses, and the trust they place in us, we help brands grow through strategic storytelling, earned media, and content that’s clear, purposeful, and grounded in reality.

As a female founder, I reflects openly on how Callista began, and what I have learned along the way.

As a female founder, I reflects openly on how Callista began, and what I have learned.

​

​"One of my dearest friends, Megan, was the catalyst behind Callista. On reflection, it wasn’t the most stable time to start a business. I’d spent the better part of 12 months knee-deep in the throes of kid-wrangling — three kids under six — while transitioning into solo parenting. While I was spinning plates, I certainly wasn’t in work mode. But dear friends have a way of knowing what you need. Megan kept emailing me work — tiny jobs here and there — which soon led to larger projects.

Eventually, it became clear I needed register a trading name, set up a business bank account… and without much thought, I had my first client.

​

Far from the perception that women working from home with young kids are running a hobby business, I learned to streamline my time, build a rhythm that worked, and create a solid income."

Growing into Callista

​

"Callista has given me the space to own who I am. I don’t try and be someone I’m not and that works.  Alignment is a key priority with new clients. Are we a fit? Do we get each other?"

You can't change my mind:

​

"In an age where content can be generated in seconds, genuine thinking, lived experience, and creative intuition matter more than ever. My creative process is something that can't be replicated by a bot."
