there are many reasons why they cost more here than elsewhere in the world.
for starters they are a dutch company with wholly owned subsidiaries in France, Germany and the USA who all pay an ex-factory cost price. Australia is handled by a distributor who would pay a distributor whole sale which i'd assume gives Koni group somewhere in the region of 25-45% margin. Then there is shipping to Australia which you'd like to think is drop ship (or even more if shipped out of Europe or USA is smaller qtys). Then there is Australian import duty, international and domestic freight forwarding, customs brokerage and GST. then once the shock is here the distributor has to pay for more marketing locally and domestic freight. Then there are other fixed costs in addition to Australia's high retail/industrial rental costs and relatively high wages. THEN the distributor has so to make a RRP that allows their re-sellers to also make money so they have a local seller network. all of that adds up pretty quickly.
unfortunately for the end customer, yes the product is the same but doing business in Australia is FAR from on an even playing field, especially with a global shop window for consumers to browse in.
