i know this is slightly OT but some shop owners need to move with the times instead of complaining. the local shops in my area complain about lack of customers... but every morning I pass by them on the way to work at 845am and they are closed. every evening I walk past them at 615pm and the are closed. these are shops selling things like business attire or homewares... things I would buy if only they were open! and I can't be the only one in that boat. so stop complaining... and meet the hours I need you to be open... otherwise I will go elsewhere (or on line). and if paying staff is an issue... get in there yourself!!! as owner!!! no worry about salary then.
I am a fan of the longer trading hours and I look at places like Singapore and Hong Kong as the example of where retail makes sense. To a certain extent, the longer trading hours there is part of the reason why those places feel so much more alive - you have people out all evenings of the week and on Sundays. It's a very different system however because businesses can afford the wages there. With one of the highest minimum wages in the world here, as well as generally the cost of doing business in Australia (tax, compliance and regulatory), I suspect it just wouldn't make business sense.
Yet somehow despite the generally depressing mood in the economy and the dollar, Australians are still finding the cash to pay one of the highest prices in the world for consumer products (the recent article about Zara being most expensive here being one of many examples). I just refuse to play the game - I no longer bother to check prices in Australia any more (not even when there are sales). It's just much safer to simply assume everything is more expensive here than overseas, so I just save all my shopping needs until I travel.
So while people are talking about the movements in the Aussie dollar affecting retail prices, I think it still comes down to this - if the dollar falls, prices will generally go up. If the dollar rises, prices will stay up (since Aussies by and large seem to be happy to continue paying whatever price is asked of them).
