No, unattended delivery is not available for champagne packages as they must be signed for by someone 18 years or older. Melbourne Metro: We will liaise directly with you to ensure someone will be able to sign for your champagne parcel or champagne gift on a suitable delivery date. For Lehmann Glass orders, unattended delivery is only possible if you authorise it with us prior to delivery. Regional VIC and Interstate: Australia Post requires a signature upon delivery. However, if no-one is home, the driver will leave a card for you to collect your parcel at your local Post Office. For all other couriers, a re-deliver card will be left for you to coordinate the most suitable time for collection with the courier.
