I was admitted in 2004. Before joining the bar in 2015, I conducted a range of litigation as a Crown Prosecutor and in a senior role with a national firms litigation team.

My particular litigation interests are general civil and commercial, professional negligence and discipline, employment law, and regulatory criminal matters (particularly health and safety and transport/aviation). I also continue to appear in some traditional criminal litigation.

I have conducted dozens of trials and appeals as lead counsel across all of these jurisdictions. I have acted for plaintiffs and defendants, prosecution and defence, employer and employee, appellants and respondents, and independently as amicus curiae and standby counsel in civil and criminal courts.

I also regularly undertake independent investigations in workplaces and governance situations.
