Tender Closing Time Converter

Australian Government approaches to market state a closing time in one jurisdiction's local time, and a response received after it is normally excluded from consideration. Three jurisdictions do not observe daylight saving, so 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. Treat this as a planning aid: the authoritative closing time is the one printed on the notice, and lodgement systems can queue under load, so aim to submit well before the deadline rather than into it.
