Recent Testimonials

"I just wanted to quickly take a moment to gratefully thank you for your time today. Your presentation today was timely, understandable (dumbed down), conclusive and accurate. And, honestly, quite entertaining! Everything our humble committee needed. As a bonus, you have taken the time to draft notes to present to my committee.

As an accountant, it actually gives me most sincere joy to learn / confirm that such fair and knowledgeable individuals form the foundation of our tax system. The manner in which you referred to the ATO represented the very integrity of a profession that I personally love and respect. It is refreshing to confirm my belief in a fair system. To be honest, good sir, it was a privilege to be in your presence."

John (Co-owner, Serviced Apartments), January 2019

"We have recently engaged Ken to assist us with a large property transaction. Ken’s knowledge of both the GST legislation and the ATO interpretations has proven invaluable. Additionally, Ken’s mantra of providing a commercial workable solution versus just theoretical advice has again proven to be invaluable. Our group will continue to use Ken for all transactional advice”.

John (CFO, Property ownership and Development Company), February 2018

"Ken I wanted to thank you for your guidance and unsurpassed expertise in relation to GST. Your approach has been practical, sensible and professional with a constant sense of urgency and client service. What has been most effective is your ability to access and work with the specific people across the ATO which allowed a quick and personalised response. I would have no hesitation recommending your services to others.”

Joe (CFO, Not For Profit Sector), December 2017

“Earlier this year we engaged Ken to review our treatment of GST on a property settlement. The transaction structure was complicated, with a number of parties involved, and the property sale transaction spanned a number of years. Ken showed a clear understanding from the start of the issues we needed to address, and methodically worked with us and the other stakeholders to map through the issues and the GST consequences. Ken also established an excellent rapport with the relevant people at the tax office and kept them in the loop throughout the process, which lasted around 4 months. The whole project turned out to be one of the most complicated cases that Ken had been involved with. We ultimately achieved a very pleasing GST result which would not have been possible without the insights and knowledge that Ken brought to the table. I would, without hesitation, recommend Ken to anyone who was facing a GST issue or wanted clarification of any GST matter.”

Alan (CFO, Property Development and Joint Ventures) December 2017

“We recently engaged with Ken Fehily on a tax matter. Ken’s knowledge of GST, and how to navigate through the ATO are unsurpassed. He is quick, decisive and takes a no-nonsense approach. He achieved results that we didn’t think were possible. I’d recommend him to anyone with a GST issue without hesitation.”

Philip (Owner, Property Development), November 2017

“I wanted to thank-you for jumping in with your advice. From the outset, I found it confident, concise and clear. It was also obviously based on deep domain knowledge. For people who find themselves, at times, in unfamiliar territory, it was comforting to have you on our side and guiding us through. Once again, thank-you and will definitely consider engaging you again and refer you to others.”

Justin (Board Chairman, Financial Services), November 2017
