Roslyn has nearly 30 years experience in local government and planning law. That wealth of experience was recognised in 2013 when she was appointed as an Accredited Specialist in this area of law pursuant to the “Nomination of Excellence Program”.

The majority of her legal life has been connected with the Land and Environment Court, practising primarily in its Class 1 jurisdiction (planning appeals); however, Roslyn also has extensive experience in Class 4 (enforcement) and Class 5 (prosecutions) as well as local government, planning and property-related experience in other Courts including the Local Court, Supreme Court, Federal Court and High Court of Australia.

Roslyn prides herself on a strong intellectual and analytical ability. She is regularly required to interpret and advise on legislation and subordinate legislation and to analyse and apply case law in that process. Her experience in a range of litigation has exposed her to a wide variety of legislation at both State and Federal levels.

Throughout her career, Roslyn has demonstrated an ability to discharge her duties in a timely and competent manner. She is a self-confessed “list keeper” which assists her to get the job done on time. She actively employs techniques to cope with the pressures of work including (almost) daily meditation and yoga practice, regular prioritising of work demands and ensuring efficiency in her work practices.

Roslyn is a great communicator. She has the ability to speak and write in plain English without recourse to unnecessary legal jargon. Her writing skills are exceptional and her advocacy is characterised by an economy of words.

Roslyn has acted for both councils and developers throughout her career and currently works in particular with Mark Cottom, Joshua Palmer and Ryan Bennett respectively in these areas. Roslyn’s continuing involvement in both areas has gained her a balance of experience rare to many practitioners.
