I head Thynne + Macartney’s Private Clients team and have over 10 years experience in succession law. I specialised in estate litigation for a number of years but more recently I have extended my practice to estate administration and estate planning.

I have considerable experience with applications to the QCAT and the Supreme Court relating to Enduring Powers of Attorney as well as guiding carers through the often sensitive and challenging issues relating to the appointment of guardians and administrators for persons without capacity. I also have significant skills and training in alternative dispute resolution including mediation and collaborative law.

I am regularly invited to speak at professional development seminars and conferences conducted by the Queensland Law Society and Lexis Nexis. I like to share the professional knowledge I’ve accumulated in my pro bono activities including lecturing QUT’s legal practice students on succession matters and contributing to the Caxton Legal Centre’s Queensland Law Handbook.

I believe that every client’s circumstances are unique, therefore I draw on my team’s experience and expertise to find the best course that fits the client’s objectives.
