I bought a similar gear with my choice of locker last week. Australia is rather unique in its import restrictions. You have to choose a shipping company who helps you with your customs duties and papers. I suggest you check
ACC customs broker in Fremantle and they will provide you with the best services at an affordable price. One should have to gather the information about the shipping process such as general criteria required for shipping the gears, documents required, cost details, details of shipping company, etc. before shipping any of the vehicle overseas or within the country.
