Australian tax law

Technically quite outstanding and very strong - the lawyers are also extremely easy to deal with and very commercial.

Chambers Asia-Pacific

As one of the leading firms in Australia for complex tax advice and tax dispute resolution, our taxation team advises leading domestic and international corporations and financial intermediaries in all areas of revenue law.

We are known for our cutting edge corporate and international tax advice to Australian listed corporates and foreign multinationals, particularly for cross-border mergers and acquisitions. Our practice covers the entire range of tax law at a Federal, State and local level, and we often work together with leading independent firms in the US, Europe and Asia.

We have significant tax dispute expertise and capability which has included preparing a number of large multinationals in the pharmaceutical, technology, and fast moving consumable sectors in preparing for appearances before the Australian Senate Economic Committee’s Inquiry into Corporate Tax Avoidance, and in representing those clients in their interactions with the Australian tax authorities.

Our client offering is distinguished with a low leverage model, which necessarily means a higher ratio of senior lawyers directly engaging with clients and their matters. This is all the more important in an area like tax – where experience, expertise, and judgment matter.


Our expertise covers both disputes and advisory matters for many major multinationals, including Microsoft Corporation, McDonald’s Australia, Treasury Wine Estates, SABMiller, Unilever, and Blackmores.

Often working collaboratively with the corporate and dispute resolution teams within the firm, our tax team provides expertise on corporate structuring, cross border investment, tax effective financing, and the myriad of tax rules affecting general business operations.
