Can I consolidate packages when shipping to Australia?

Are there any consolidation restrictions when shipping to Australia?

Consolidation (packing multiple purchases into one shipment) to Australia is allowed. However, all contents must be from the same seller to avoid shipments getting returned.

Ebay, Amazon and other marketplaces are NOT considered a single seller. Multiple items from these marketplaces would need to ship in individual shipments, based on the actual sellers (the actual seller who sold each item).
