Qantas Credit Union's core banking platform will be completely replaced by mid to late 2017 as part of a thoroughgoing overhaul of QCU's infrastructure.
The credit union will replace its existing platform with Infosys' Finacle in a project that will also involve delivering a new range of digital products for QCU.
The project will include a new mobile banking and tablet app, an upgrade to the QCU's online banking platform, and implementing peer-to-peer payments and digital wallets, Infosys said.
Infosys subsidiary EdgeVerve will deliver Finacle 'as-a-service' to the credit union.
"Our partnership with Infosys Finacle is an exciting one for us," QCU's CEO, Scott King, said in a statement.
"Firstly, it will deliver both short-term benefits and staggered releases, transforming our core system, online, mobile and tablet banking over the next three years. Secondly, this partnership will help us deliver experiences that make banking easy, more personal and opportunities that empower our members to bank with us the way they want to.
"Lastly, the partnership will see increased efficiencies, streamlining of processes, advanced automation, better insights and reporting, thereby, delivering a competitive edge."
QCU has 95,000 members and $3b in assets.
