Info from Deb at Austorient Motorsport Logistics.

Effective Jan 1st 2010 sees the introduction of reduced (or phasing) rates of duty for numerous areas of the Australian Customs Import Tariff.

The duty rate is calculated at the date the Customs Entry (Import Declaration) is submitted, and as such to take advantage of the favourable duty rates if applicable, shipments should be managed to either arrive in Australia after 1st January 2010 or in the case of FCL consignments, as required, Austorient to move your shipments into a Customs Underbond facility until the new year, then entered and cleared at the reduced duty rate as applicable.
