What we're about


We’re not just bookkeepers, we are a business service guided by our core values.


Meet Michelle

Principle & Founder

“The greatest lesson I’ve learnt over the years is passion isn’t enough to run a successful business.”

Having grown up in a household of entrepreneurs, Michelle learnt from a young age what really goes on behind the scenes of a small business – from the triumphant successes to the challenging tribulations.

What she found was that while most business owners hone in on their craft and deliver exceptional products and services, they often lacked the time and skill to efficiently handle the financial obligations and compliance of their business, causing all their hard work to go down the drain.

With a growing number of businesses in the Hawkesbury and surrounding areas, but a lack of services available to support them, Michelle made it her mission to help local businesses along their journey to success – and in 2010, established Oakleaf Bookkeeping Services.



Over the last decade, Michelle has been trusted by more than 30 businesses including farmers, retailers, builders and all kinds of trades, to guide them towards financial success with her unique hands-on approach, honesty, care and unwavering desire to make their lives easier by removing some of their biggest pain points.

Michelle is also supported by a highly experienced team of bookkeeping professionals with over 30 years of financial industry expertise, diverse accounting knowledge and qualified as BAS Agents, compliant with all Tax Practitioners Board Education requirements.

Why the Mighty Oak

The Oak tree is considered a symbol of prosperity, longevity, knowledge and success, growing slowly but with towering strength. In many cultures, it was used as a meeting place to discuss business and matters of the mind.
