About us.

We do accounting…but better.

We’re an advisory first accounting practice which means that we focus on value-add, practical and timely advice to help you grow your business, manage cashflow and achieve your goals.

Our mission.

To help business owners achieve the outcomes that are important to them by providing practical, actionable insights and exceptional support.

What we’re about.

Outcomes focussed

We’re obsessed with helping our clients achieve the outcomes that are important to them. Whether that’s shooting for the moon by launching a unique endeavour, building a successful family business or enjoying a side hustle, we’ll be right by your side to provide the financial insights and personalised advice to help you get there.

Trusted relationships

We aren’t interested in seeing you once a year to lodge a tax return. We get to know our clients, invest time in the relationship and understand their business so we can provide relevant advice.

Complex made simple

You can know everything about accounting and tax but if you can’t communicate it in a way that people understand, it’s worthless. We believe in providing great quality advice, in a simple, no fuss, easy to understand way so that even if you’ve never looked at a set of financials before, you can know what’s going on. 

Meet our founder.

Matt Byrne Director

G’day, it’s Matt here, head honcho at Day One Advisory.

I founded Day One Advisory with the view to creating an accounting practice that was focused on helping business owners like you achieve the outcomes that are important to you.

I started my career working with small businesses owners before spending some time with the big end of town providing complex tax advice. As much as I loved working with listed companies and large private groups, making a difference directly for a small business owner is significantly more rewarding.

If I’m not working, I’m either at the park walking our dog Frankie, working on the never ending renovations at home or at the pub with friends (all of the above likely being done with beer in hand).
