Penny oversees the legal function of MSS Security and its related Australian entities.

With more than 22 years of legal practice under her belt, she has exposure across a range of service and customer-oriented industries including retail, FMCG, fitness and ICT. Her security experience commenced in the late 1990s when she worked on a project setting up a security franchise on behalf of a large direct selling corporation. She joined MSS Security on a temporary basis from 2012 to 2013 and returned permanently in early 2017 as General Counsel. Penny has also worked for a top 5 legal firm, a government regulator and a number of companies – both private and public – sitting on the leadership teams of four of these.

A results-oriented, pragmatic and commercially focused generalist practitioner, Penny brings with her a wealth of commercial experience across contracts and transactional work, competition and consumer law, corporations law, intellectual property, privacy, dispute resolution, workplace law, compliance, governance and risk management.

Penny holds undergraduate degrees in Law and Social Sciences from the University of NSW and her post graduate qualifications include a Master of Laws, also from UNSW, and a Graduate Diploma of Law from the University of Sydney.


In the spirit of reconciliation, MSS Security acknowledges the Traditional Custodians of Country throughout Australia and their connections to land, sea and community. We pay our respect to their Elders past and present and extend that respect to all Aboriginal and Torres Strait Islander peoples today.
