Not exactly. Here this is gonna be boring and put you to sleep but whatever.
In australia a long-ish time ago there was a boom in mining. But that shit was really dangerous and risky so people got paid BIG BUCKS. Well then what started to happen was more and more people became miners and more people made big bucks. So especially in mining towns things got expensive because the miners could afford it. Its still the same now so the australian dollar, although technically like 1.1 us dollars has a different stigma around it so they are not equivalent.

This is pretty incorrect in terms of why consumer goods are more expensive in Aus. While you could suggest the resources boom has led to inflated prices, based on the idea that higher national income leads to an increase in aggregate demand and thus prices rise as the increase in demand exceeds the increase in supply, that certainly does not explain the whole situation.
Australian cities tend to have incredibly high rates in terms of renting commercial space in comparison to other cities, and furthermore our minimum wage far exceeds that of the US and many other countries. Combine this with relatively high company taxes and mandatory super-annuation contribution of 9% and all of a sudden businesses have to fork out a lot of money just to operate. Thus, businesses must raise the prices of their goods, shoes in this instance, in order to remain a profit margin. Furthermore, due to domestic protection, imported shoes have a tariff of 5%, meaning that businesses have to pay an extra 5% of the cost of the shoes when they import them. This is then passed on to the consumer so the business does not lose money through raised prices.
I'm sure there is more to it but I'm just writing this to procrastinate studying for my exam tomorrow, so I'll stop here.
