Take a look at what some of our clients have to say!
Trekk Advisory came highly recommended by a colleague and I am so pleased that I made the move. I am a small business owner and tax and numbers completely overwhelm me. I finally feel I have the support, very thorough feedback, all questions answered and the team are extremely generous with their time.I can’t speak highly enough of this firm and will strongly recommend to family and friends.
The team at Trekk came highly recommended to us several years ago, and we can’t imagine growing our business without them. They are brilliant at what they do, care about their clients, and, with their help, we have become better business owners with a healthy work-life balance.
I have dealt with Gavin and his team for more than 10 years now, as both Overells and Trekk. They are well organized, professional, technically very capable and respond promptly to all requests made for assistance. I highly recommend Trekk as an accounting / advisory service to both businesses and individuals.
We've partnered with Gavin and the team at Trekk for a few years now and really value the personal attention and responsiveness we receive from Trekk. They genuinely regard your business as if it was their own. Highly recommend. Saltair Modular

I would highly recommend Gavin and the team at Trekk Advisory to anyone looking for a professional accounting team
Tony and his team have been our business advisors and accountants for the past ten years and, in this time, have provided excellent advice and service that has enables us to grow our business consistently. We were also facing strong headwinds due to the pandemic, and again the advice and assistance offered was the first-rate.
I have been working with Tony Madden and the team for many years. Their recent re-branding to Trekk Advisory has was a change but the great accounting services they provide to my company has not changed. I would highly recommend them as a professional accounting and advisory partner.
Tony and the team at Trekk are an essential part of our business for over 10 years. We constantly challenge the team to demonstrate value and they consistently deliver.
I have entrusted all my Financial Affairs with Trekk Advisory now for over 10 years. Tony and David have always been available to discuss my business and personal financial needs.

Our Brisbane Team
In a sea of big-city accountants, we're a little bit different. Human first, advisors second.
Our Brisbane accountants are passionate about our clients and their businesses. Our accountants are here to give business advice and help you to harness the power of numbers and take your venture to the next level.
Tony Madden
Director & Business Advisor
B. Bus, CPA.
Tony is a director of Trekk and based in our Brisbane office. He works heavily in the advisory space for his clients, focusing on strategic management consulting, mentoring, and resource planning with a driver of making a difference in their businesses and lifestyle. Tony has key strengths in building teams and is an active listener in working to address the pain points in clients' businesses.
He had a passion for small business from a young age due to being brought up with a family of business owners. He's worked with larger corporations and not-for-profits, but he's always drawn back to helping and supporting small to medium (SME) businesses. That's why he's a Director of Trekk, because supporting SME is something we are all passionate about here.
Outside of work, Tony has an active family with three sons that love sports, music and socialising. He enjoys having a drink and some laughs with mates and working on restoring his old EH Holden. He’s a passionate Eels NRL and Reds Rugby supporter with a love of vintage and muscle cars, 80’s Rock and keen runner (for the mind & body), Tony also has a laugh by 'acting the goat' at any event where he can embarrass his kids.
Gavin Weller
Director & Business Advisor
Gav is a Director of Trekk and operates from our Brisbane office - helping his client's in the advisory space in planning, strategy, structure, and taxation. He loves being able to work closely with both his clients and his team to help them achieve their goals. The best part of his job is that each new day is interesting, challenging and rewarding because of the great people he gets to work with.
He is a massive fan of all sports and no doubt wishes he could have been a sports star or commentator. Unfortunately for him, he’s not good enough or impartial enough for either but he very much enjoys continuing to play soccer and tennis in the meantime. There's more to him than sports though... He loves music and going to gigs and theatre with his wife.
Gav goes by the saying "Life is short – enjoy and appreciate this moment" and "Back yourself – some days you kick and some days you get kicked – that’s rugby". This metaphor for strength and resilience helps him get the best out of each day.
Anna Averianova
Accountant
M. Bus
Anna is based in our Brisbane office and is a wealth of knowledge in the SMSF space. She has worked in the SMSF industry since 2006 and has a huge list of certifications and memberships in tow. It makes her day being able to work alongside great co-workers and managers, as well as seeing her clients' satisfaction.
She enjoys traveling and exploring with her family. During COVID Tasmania became the dream place to visit as it combines history and beautiful nature. She is looking forward to returning to Europe in the near future to soak up the culture. Anna believes in making the most of what you've got, and her favourite quote is by Serbian Patriarch Pavle ‘When a man is born, the entire world is happy, and only he cries. But he should live in a way, when he is dying, the whole world should be crying, and only he smiling’.
John Harris
Accountant
B. Bus (Accy)
John is one of our senior accountants in Brisbane. He loves assisting everyday Aussies to achieve their desired results - be it in business or with their investments. Starting his accounting career in 2013, John worked at a firm in South Brisbane as a graduate accountant. It wasn't long until he stepped into the shoes of Senior Accountant / Client Manager and then joined Trekk Advisory in 2021!
Jumping deep into some heavy metal (or the latest Jo Rogan Experience Podcast) when tackling the next big project, you’ll find John tucked away at our office in Newmarket working on getting the best results for his clients. He has a special interest in property investors (be it long term hold or development) and is aces on the tools when preparing financials and tax returns.
He’s pretty sure he was a fish in another life - Never missing an opportunity to get in the water - and also enjoys Taekwondo, bike riding (pedal power, of course) and fishing! In fact, his favourite family tradition is a Good Friday lunch paired with a day of fishing with his family.
John’s got some big things on his bucket list... A Bike ride up Alpe d’Huez. Skydiving Fox Glacier in New Zealand. A motorbike tour through Vietnam and Cambodia... Just to name a few! And he believes “The greatest pleasure in life is doing what people say you cannot do. Go out and do what you are passionate about!”, which is one of his favourite quotes.
If you’d like to talk about your business goals, investments (or the latest season of Rick & Morty), reach out to John today!
Jen Perrin
HR Manager
B. Bus
Jen's been around since 2011 and morphed into a bit of a jill-of-all-trades for our Brisbane office. Jen has a Bachelor in Business (Human Resource Management) & is a certified member of the Australian Institute of HR.
Jen believes that human capital is an integral part of any business and plays a key role in providing an organisation with a competitive advantage within its industry. People and culture are her jam! Jen can empathise with small business clients that HR compliance, attracting talent, keeping staff engaged and motivated and retaining good employees is a difficult task. If she can remove the stress and anxiety around these components for her clients that’s a win!
Outside of the hustle and bustle in the office, Jen is all about the slow and steady life. She enjoys settling into her hammock reading a good thriller or fantasy novel, enjoying the sound of the ocean and sand between her toes. She loves her sports and is a passionate Dragons supporter, during the week she’s off playing netball and taking her pooch Wendell (staffy x kelpie) for a stroll.
