As far as shops I am In TAS I cannot help, But as for Boots I recently bought my a pair of Asolo TPS 535 and am extremly happy. Just my 2 cents.
Apparently aussies have wide feet compared to europeans, must be our convict heritage

But I agree With Tofu_Imprint, reviews, forums and shortlist. This can become a bit tedious but worth it when you have a good pair of boots to set you free...
