No Fuss, No Frills

My name’s Katrina, and I make voice, speech and public speaking training simple. 

I work with actors, professional speakers, corporate leaders, and healthcare experts, using evidence-based strategies to help them develop genuine comfort, confidence, and competence in communication.

My training process is practical and joy-filled, shifting limiting habits & self-beliefs by building presence, body, breath, voice, and speech skills that you can trust in public and under pressure. No fuss, no frills: this is specialised voice and speech work that works.

When I’m not teaching actors or coaching corporate and NFP groups across the country, I’m working with my 1:1 clients either in person at Studio Vox (my dedicated studio space in Woolloongabba, Brisbane) or online.

The speakers I train walk away from the work free of fear and affectation: sounding, looking and feeling like their most authentic selves. Whether you’re working to a tight deadline or looking for long-term change, I’ll get you speaking up and out in no time.

Working with Katrina has been transformative for my confidence in speaking. Before our sessions, I often felt nervous when addressing leaders or presenting to large teams. Her approach not only improved my voice and speech techniques but also made me feel empowered to express my ideas clearly. I now walk into meetings with a newfound confidence, ready to engage and inspire my audience. The skills I've gained have become an integral part of my development plan, and I genuinely feel like I can hold my own in any conversation.
Bec WrightEmployee Engagement and Experience Specialist, Hastings Deering
Loved working with Katrina! She was full of knowledge and insights and was able to break down that knowledge so that I could apply it with my voice. Working with Katrina gave me courage and confidence in my voice - so much so that I was able to record a 70,000 word book into an audio book. Thank you Katrina!
Turia PittBest-selling author, coach and occasional Hard Quiz answerer
Before I met Katrina in an online workshop, I had no idea there was such a thing as a voice and speech coach. However, within a few minutes I experienced the transformation Katrina was able to achieve in my speech and voice presentation, and I decided to do a course with Katrina to properly develop skills in this area. I am glad I made the commitment. I am aware of my breathing, and am now more attentive in my listening and communication skills. I feel more confident in my communication skills, and I would highly recommend Katrina and the courses she offers to anyone that feels verbal communication is an important part of their work or daily life.
Peter SprekosFounder and Director - By Design Accountants & Business Advisors
Katrina from Simply Speech delivered a public speaking workshop for our staff at Kimberley Aboriginal Medical Services (KAMS), and the feedback was overwhelmingly positive. Participants left feeling more confident and better equipped to manage nerves, engage their audience, and speak clearly and with structure. We would highly recommend Katrina and Simply Speech to any organisation looking to strengthen their team’s confidence and effectiveness in the workplace.
Lylla LeaupepeLearning & Development Coordinator, Kimberley Aboriginal Medical Services
So amazing to attend Katrina's 'Effective Communication' masterclass hosted by the Australasian College of Physical Scientists and Engineers in Medicine (ACPSEM) - a very different (but VERY important) skill set that I feel as physicists we just don't work on enough: clear communication and the ability to connect with your audience cannot be understated! A completely inspiring and interesting workshop!

Katrina's guidance has transformed my speech delivery and facilitation skills. She's equipped me with tools for tone, movement, breath, body language (and much more), enabling me to articulate myself with confidence and connect deeply with my audience. Her expertise is a game-changer, and she's been pivotal in making me a more impactful speaker.

I need to use my voice in many roles - from caring for patients, to teaching trainees and facilitating conferences. Katrina has given me invaluable skills in professional speaking and personal presentation. I am now a much more clear and confident communicator. Thank you!
Dr. M.B.Doctor & Medical College President
I highly recommend Simply Speech, Katrina is an amazing speaking coach. I sought her help with doing my first ever presentation for work and I had no previous experience at all with public speaking. Her help with formulating the presentation and then delivering it were invaluable and I absolutely could not have done it without her. Having had her coaching gave me the confidence to get up and speak and I actually enjoyed it and had fantastic feedback! It was such a positive experience. If you want to learn the skills to do public speaking then Katrina is the answer - she is fantastic.
Dr. Deborah WebbVeterinarian
Katrina was a delight to deal with from start to finish. She made time to really understand what we were hoping to achieve, and then designed and delivered a fantastic, engaging half day session for our group of women participants. They loved it – and were able to immediately put into place what they had learned to become more confident and skilled speakers. Highly recommend Katrina and will definitely engage her for our next program.
Georgina CopeAustralia Awards 'Women Leading and Influencing'
The data storytelling workshop was a game-changer for our team. Katrina has a unique way of making complex concepts accessible and relatable. After the session, I noticed a remarkable shift in how my colleagues present their ideas. They now know how to weave narratives around data, making our presentations not only more engaging but also more impactful. The team feels more empowered to communicate their value in any room, and the feedback has been overwhelmingly positive. It’s incredible to see how our presentations have evolved, and it’s all thanks to Katrina's guidance. We will definitely be using this workshop again in our business.

Katrina from Simply Speech has been an incredible gift to our community, empowering our members with the skills and confidence to find and use their voices. Through her masterclasses on effective communication, she created a space where participants felt seen, heard, and equipped to express themselves with clarity and authenticity. The tools she shared were easy to connect with and immediately put into practice. Her approach is trauma informed, insightful and compassionate. We are deeply grateful for Katrina’s contribution and the impact she has made in strengthening the voices of those who need it most.
Danielle MifsudExecutive Director - Humans of Purpose Academy
Katrina is an excellent presenter & speaker. It's one thing being so gifted in all manners of speech, but sharing those skills unreservedly and really caring about your progress is both humbling and extremely inspirational. I would thoroughly recommend Katrina to anyone who wishes to take up or improve their presentation and speaking skills.

Katrina brought to life my voice and projection which I did not know existed previously. Now I can speak with clarity and volume to an audience. She is very knowledgeable and an excellent coach, a real pleasure to work with!
Karl UngMicrosoft Azure Partner Manager
Katrina was attentive and present during each of our sessions. She helped me improve my voice, get over a lisp and even start singing. I felt at ease during each session and I enjoyed the process of building my craft from the bottom up. I would thoroughly recommend Katrina.
JRDSurgical Registrar, Royal Darwin Hospital
We just finished up our last show of the term and just wanted to say thank you so much for the session we did a few months ago. It has made the world of difference on tour. I've used your advice and tools everyday and I really don't know what i would have done without you.
Zoe Schramm Shake & Stir Theatre Company
"Working with Katrina for eight weeks was truly transformational. Public speaking had always been a deep-rooted fear of mine, something I actively avoided for years. But from our very first session, Katrina created a safe, supportive, and judgment-free space where I felt seen and understood. She validated my fears while giving me the confidence to push past them with practical, actionable steps. I truly could not have done this without Katrina. She is not just a coach; she is a mentor, a cheerleader, and an incredible teacher who knows exactly how to bring out the best in her clients. If you’re looking to overcome your fears and step into your confidence as a speaker, I cannot recommend Katrina highly enough!"
