About Us

HDT Chartered Accountants (formerly Hanlon Davies) has operated as an accounting practice for over 35 years. Tax laws and technology have evolved significantly over this time and the practice has continued to evolve and keep abreast of the latest changes. What has not changed is our ability to build excellent relationships with our clients and to deliver timely, easy to understand advice in a world where accounting and taxation is becoming more complex.

Our client base ranges from individuals and owner-operated businesses to medium-sized family-owned businesses as well as investors, property developers and retirees. Our clients operate in various industries including:


These clients are based all over Western Australia, predominantly in the south-west including Busselton, Dunsborough, Cowaramup, Margaret River, Nannup and Bunbury. However, we also have clients in Perth, Fremantle, and in the Mid-West, Pilbara and Kimberley regions. In the digital age, technology enables us to assist clients in any location.

Our professional staff are members of Chartered Accountants Australia and New Zealand (CA ANZ) and Certified Practicing Accountants (CPA) Australia. We are also members of the Taxation Institute of Australia and the National Tax & Accountants Association. These memberships provide us with a great resource base for training and knowledge.

Tax Audit Insurance

In the event of an Australian Tax Office (ATO) audit or review, or a review by another government agency, the insurance will cover all professional fees relating to providing the required information to the ATO and responding to any further enquiries.
