Kate has a predominantly public law and regulatory law practice.

Kate has also appeared in a number of special leave applications and Full Court hearings in the High Court. For example, Kate appeared for the plaintiffs in two recent High Court cases on the operation and application of the power in s 51(xix) of the Constitution: the ground-breaking case of Love v Commonwealth of Australia (2020) 270 CLR 152 (where she was led by Stephen Keim SC) and, Chetcuti v Commonwealth of Australia (2021) 95 ALJR 704; [2021] HCA 25 (where she was led by Georgina Schoff SC and Georgina Costello SC).

Otherwise, Kate regularly appears, both led and unled, in federal and state jurisdictions at trial and appellate level.
