What’s the right setup for rural / NT / TAS deliveries?

Rural Australia, Northern Territory, and Tasmania need special handling because (a) Australia Post SLAs are 5-10 business days vs 1-3 for capital cities, (b) some couriers (Couriers Please) don’t deliver beyond metro areas, and (c) freight to remote NT / TAS often costs 3-5× metro rates. Our standard build: (1) postcode-based shipping zones in Magento with separate rate tables for metro / regional / remote, (2) carrier fallback chain (Australia Post Express → StarTrack → Sendle → Aramex) configured via ShipperHQ, (3) delivery-time messaging on PDP + cart so customers in remote NT see “5-10 business days” up-front, (4) optional freight surcharge for parcels > 5 kg to NT / remote TAS, (5) signature on delivery default for rural to reduce lost-parcel claims.
