Can you explain why prices are always high in Australia? It's close to asian countries which makes the products. Does the government rip you off?
There are several reasons, with proximity to Asia not being one of them. Unless you are using airfreight, if you are on the worldwide container network, it costs the same to within a few percentage points to send a container from one port to any other location in the world. E.g. sending a 20ft container from Taiwan to Los Angeles or New York, London, Stockholm, Berlin, Moscow, Paris, Cape Town, Delhi, Sydney, Auckland is roughly the same price.
The major drivers are volume, local customizations, and tighter consumer/merchantability laws than somewhere like the US. For example, being a smaller market, they can't use volume to cover costs or hit profit targets, they can't make $1m profit by selling 1m units with a $1 profit margin, since they might only be able to sell 50,000 units, therefore will need to increase margins by 20-fold. Tighter consumer affairs laws means higher costs to satisfy those laws, it's much easier to return a product due to not meeting statutory warranty and merchantability criteria, therefore that costs more money to handle which have to be paid for by increasing prices.
There's a GST, a VAT, but it's only 10% compared to many EU countries 25% VAT. However, there are no additional local sales-taxes that have to be paid that some countries allow individual states and even towns to levy.
Local customizations and regulations cost money. So while to meet a US FCC regulation might cost $1m spread over 10m units, it might still cost an equivalent amount, $1m, to mee Australian equivalents, but they have to recoup that $1m from 500k units instead of spreading it over 10m units.
And, finally, because the companies/businesses just can. It's a captive market. Often there might be a single distributor for the entire country (due to the aforementioned volume issues) rather than a dozen competing against each other like in Europe or North America. If I was a local business could I maybe buy my product from the Singaporean distributor rather than the sole, ripoff charging Australian distributor? Sure. But then I'd have to pay freight from Singapore (which already had to pay freight from Taiwan to get it to Singapore), I wouldn't have the backup of the manufacturer because it's not an 'Australian SKU', therefore that'd cost more to have to cover that support.
