Cost of International 220v WiFi Precision Cooker

Hi

Hi, I am in Australia and I would like to purchase a precision cooker with WiFi, however I have noticed that the cost of the 220v versions of the same product are $50USD. I already have to go through the drama of shipping costs as well as exchange rates to get to the things I want to buy, so I’m just wondering what this 25% increased cost is due to?
