Answer
What time do Australian Government tenders close?
At the date and time stated on the notice, in one jurisdiction's local time, most often ACT local time. A late response is normally excluded regardless of merit.
Australian tenders state a closing time in the local time of a single jurisdiction. That is the authoritative instant, and the buyer has limited discretion to accept anything lodged after it.
Time zones make this genuinely risky. Australia spans several zones and three jurisdictions, Queensland, Western Australia and the Northern Territory, do not observe daylight saving. For roughly four months a year Brisbane runs an hour behind Sydney and Perth is three hours behind. Adelaide and Darwin sit on half hour offsets year round. A 2pm ACT closing time is 11am in Perth during daylight saving.
Lodge well before the deadline rather than into it. Lodgement portals queue under load, and everyone else is submitting at the same moment.
