Gillian Marks, the former General Counsel of DMO, enjoys professional and personal challenges. Professionally, she spearheaded reforms at DMO and increased the number of female executives. Personally, she has walked the challenging Kokoda Track in Papua New Guinea twice, once with her daughters. The first time she walked it, she attended a WWII memorial ceremony where her father had served. Walking the track helped her understand the hardships faced by soldiers during WWII.
