Megan has a particular passion for social justice and in expanding opportunities to access justice which is reflected in her commitment to legal aid work and volunteer legal work.  This was also reflected in her Honours and Masters study which looked at environmental justice.  This was also the reason she has joined the team at Cooper Legal who are committed to social justice and providing high quality legal services to those most in need of them.  She undertakes criminal, parole, and human rights work.  She is an experienced lawyer with category 3 legal aid provider status in criminal and civil legal aid with extensive court experience in the District Court including judge-alone and jury trial work.  She is also an experienced duty solicitor and has PDLA status.  She is also available to take private instructions.
