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.
