Vault Systems was chosen to host the digital identity solution last year and its head, Rupert Taylor-Price, apparently had no inkling just three months ago that he would be playing no further role in the project.
At the time, Taylor-Price told iTWire that his company was more involved in "the automation, the cloud technology, the delivery of the actual infrastructure and environment that sits behind that".
The Digital Transformation Agency, along with the Australian Tax Office and DHS would run Govpass, he said.
A spokesperson from the Digital Transformation Agency said in response to queries from iTWire that it had engaged Canberra-based IT company Gulanga in January 2017 to host the digital identity system prototypes for 12 months. Vault Systems was the wholesale provider for Gulanga.
"Following the decision that DHS and ATO will operate the digital identity system’s components, the two agencies assumed responsibility for hosting these components," the spokesperson said.
"The DTA continues to use Vault for hosting in relation to other projects and initiatives."
iTWire has sought comment from Taylor-Price about the reasons for his company suddenly being excluded from the Govpass system.
The trial in October will use the ATO's new online tax file number application service.
Govpass was allotted $92.4 million in the 2018-19 Federal Budget so that the solution could be taken to completion. About two-thirds is new money and the balance is coming from the ATO and the DHS, with the former absorbing $25.9 million and the latter $5.6 million.
