Business Representative in Sydney Australia

Look for someone who can represent my business in Australia. I already have a fulfillment center i ship the goods to but i need a local Person who can represent my company and receives the goods as my customer so the goods can be cleared customs and go to fulfillment center i have already been sending shipments on regular basis but recently have been notified by my broker in Australia that customs now require someone in Sydney Australia to have these goods cleared for me by talking to my broker who will explain you everything. Now i will be sending shipments once or twice every month as required so i'm looking for Permanent Source to rely on.
