Former chief digital officer at Revenue NSW, Kathleen Mackay, took out the number one position in the 2021 CIO50 Australia, which celebrates the achievements of Australia\u2019s top 50 technology and digital chiefs.\nThe 2021 CIO5o Australia awards ceremony was held as a hybrid event at Sydney\u2019s Taronga Zoo on November 18.\nNumber 1: Kathleen Mackay, Revenue NSW\nKathleen Mackay was the first woman in the CIO50 Australia\u2019s six year history to grab the number one position in the CIO50 list, a huge achievement in a sector that is dominated by men, particularly at the most senior levels.\nMackay and her 300-strong team led one of the first large-scale implementation of machine learning in the Australian public sector. The Work and Development Order Program identifies around 15,000 vulnerable people each year, diverting them from the standard debt collection process and towards opportunities to pay off fines such as participating in unpaid work, courses, counselling, or treatment programs.\nIt\u2019s a complete change in thinking in how governments engage with citizens. Mackay and her team clearly took a more compassionate approach to getting money from people that it owed to the government. It\u2019s one also that takes into consideration the stresses that disadvantaged and vulnerable Aussies have faced, particularly since the onset of the COVID pandemic last year.\nNumber 2: Dr Steve Hodgkinson, Victorian Department of Health\nA CIO50 Australia stalwart, Dr Steve Hodgkinson, the chief information officer at Victorian Department of Health is one of the most respected champions of agile methodologies in the Australian public sector. The Platform+Agile approach he helped develop is now being copied and adapted by other state government departments, local government councils, and health services.\nIn the past 12 months, Dr Hodgkinson and his team has delivered more than 100 new technology projects and initiatives with a total investment in excess of $140 million, a record for any Victorian Government department.\nNumber 3: Helen Clifton, Australian Broadcasting Corporation\nNow the media industry has undergone rapid change in recent years barely noticeable from what it was even 10 years ago. The effects of digital disruption have been widespread and brutal.\nHelen Clifton and her team have transformed the ABC into a digital powerhouse with a range of apps that have generated audience metrics that are the envy of commercial media companies.\nOther senior technology and digital executives who were in the top 10 this year included:\n\nBen Fitzgerald, chief technology officer, Tennis Australia\nJennifer Rebeiro, chief information officer, Greater Western Water\nMichael McNamara, chief information officer, Services Australia\nJohn Vohradsky, executive general manager of IT, IRT Group\nMichael Ciavarella, general manager, technology, Swimming Australia\nGeorge Gorman, chief technology officer, Janison\nGordon Dunsford, chief information and technology officer, NSW Police\n\nAll the CIO50 Australia profiles can be found here.\nCIO Australia congratulates all the technology and digital leaders who featured in this year\u2019s CIO50 awards.
