All prices are in Australian dollars (AUD) and include GST (10%). GST is chargeable only for Australian customers.
International customers will see a discount applied to their shopping cart to reflect the sale price less the GST component. GST inclusion is calculated on the shipping address not on the purchasing address.
To calculate ex GST prices divide the sale price by 11 and multiply by 10 eg $110 / 11 * 10 = $100.
