Two brands are available, Larnec & Taurean. Both Australian Made. 
Manufacture time varies from 10 working days to 25 working days depending on the model of door. The Standard shed doors like the Larnec Sentry 650 and Taurean range of doors tend to be at the 10-day end of the supply range. The heavy-duty, more customised models take longer so please ask if your timeline is critical.
If your site or home is deemed remote by the freight forwarders it may be necessary to collect from a regional centre near you.
