The Australian Information Industry Association said Fitzpatrick had tendered his resignation, effective from 23 November, for an opportunity with an "early-stage Australian tech start-up".
The resignation was formally accepted by AIIA chairman, John Paitaridis, who expressed his gratitude for Fitzpatrick’s service to the ICT sector and the association’s members, since joining as chief executive in February 2016.
Paitaridis said: "Rob has served with integrity, passion and resolve for more than two and a half years to successfully further the objectives of the AIIA to represent and advocate for technology-led innovation in Australia’s digital ecosystem.
“The AIIA has never been more critical to Australia’s future. As technology transforms every aspect of our lives, the AIIA’s mission is to work with industry and government to help shape policy and encourage investment and collaboration in Australia with a strategic focus including skills, innovation and digitalisation of the economy.”
Fitzpatrick said: “I’m extremely proud of the AIIA and its achievements during my time as CEO.
“Together with the Board and alongside my team, we put in place a multi-year strategic plan to bring the technology industry together, and drive a policy-focused agenda, build strong and positive relationships with corporate Australia and recognise and support true digital innovation through 25 years of AIIA’s iAwards Program.
“My passion to fuel Australia’s future social and economic prosperity through technology innovation has never been greater and I will continue to be a strong supporter of the AIIA. I am committed to a seamless transition phase over the next few months to ensure my successor and the AIIA have the greatest opportunity for continued success."
The AIIA Board notes having "commenced the search for a new CEO, and is committed to recruiting an experienced, high caliber leader to continue the important mission of the AIIA".
