As CIO, Tim will be responsible for the Group’s enterprise technology functions, technology and data security, data governance, technology infrastructure and delivering ASX’s multi-year technology modernisation program and capability uplift.

ASX Managing Director and CEO, Helen Lofthouse, said: “Tim is a highly skilled technology transformation executive who brings to ASX more than 25-years’ experience in business and technology roles across Australian financial services.

“I am pleased to be making this announcement after a competitive global search with very high quality candidates. Tim’s deep expertise in technology and project execution in the financial services industry will be invaluable as ASX looks to contemporise its technology and deliver critical market infrastructure.”

Mr Whiteley was appointed to lead the ASX’s CHESS Replacement Solution Design work in November 2022 following the Group’s decision to reassess its CHESS replacement project.

Ms Lofthouse continued: “Importantly, Tim’s appointment as CIO provides continuity of technology leadership for CHESS replacement.

“The CHESS Replacement Solution Design team will continue to be led by Tim while he puts in place a new leadership team structure for the CHESS replacement program. As CIO, he will also have accountability for delivery of the technical aspects of the CHESS replacement program.”

Prior to joining ASX, Mr Whiteley held positions at Westpac and Commonwealth Bank, leading large enterprise-wide technology transformation projects.

Today’s announcement follows the 17 March announcement that ASX would create a dedicated Technology division, splitting the Group Executive, Technology and Data, and CIO role.

Dan Chesterman continues as Group Executive, Technology and Data, responsible for maturing ASX’s enterprise data capability and growing ASX’s customer-facing Technology and Data business - ASX’s fastest growing business.

Ms Lofthouse added: “I would like to thank Dan for his considerable efforts to manage what has effectively been two significant executive roles.

“This change will enable Dan and his high performing team to focus their energy on growing new areas of data and technology innovation.”
