No containers are opened and processed on the wharf/terminal.
You should have information on who your shipping agent is, they are the people that collect the containers off the wharf and open them and sort out all the import/ duties etc etc. and then split the contents off a container by consignment ready to be picked up by you (be quick, storage fees are pretty high) or have them delivered to an address of your choice (at your expense.)
Companies like Toll, CCS and Patrick (which also operate the conatiner terminal in Fremantle) are the companies that do these sort of things..
Best source of info is the company you buy your stuff from..
good luck
Get the supplier to provide a quote under shipping / INCOTERMS of CIF. This is price includes Customs, Insurance & Freight (CIF). It appears you may have been quoted FOB (Free On Board) - that means you are responsible for the goods once it is on the ship
Contact a Freight Forwarder who will assist on getting the goods through Customs / Insurance etc. They should also be able to arrange transport to your destination, noting that they do this all day everyday they will have contacts for local transport.
