The closely-watched tender, to encompass supply of enterprise-level Linux system software, application software and associated services for desktop and server environments, had provisionally been listed for release on 30 August.
A spokesperson for the Department of Commerce told ZDNet Australia the tender had been delayed due to the time required to pull together meetings with state government agencies and suppliers and include the feedback from those sessions in the final tender document.
A panel of suppliers is expected to be pulled together as a result of the tender's issue.
