You are right, the Australian dollar is at approx' 75c US at the moment which is slightly lower than it was a month or two ago, and that is the problem.
This problem is two fold, firstly with the perception within the American market that the potential purchasers in the US have with the comparative pricing of Australian goods landed in the US compared to locally produced products, and secondly the main concern is that it was only a couple years ago that the Australian dollar was only valued at approx' 55c US so that this change in the price comparison between US and Australia dollars has meant that it appears that Australian prices for the same goods have dramatically increased in a relatively short period of time, whereas in reality they have stayed the same and it is the exchange rate that has changed.
Look at the comparison, an item that costs $10,000.00 Australian right now would cost approx’ $7,500.00 US (plus freight, duty etc at the same greater exchange rate), a couple of years ago the same item at $10,000.00 Australian would have only been $5,500.00 US, (a comparatively huge increase).
To be able to compete with prices of products manufactured locally within the USA, especially fibreglass, we in Australia have to have a favourable exchange rate (i.e. it needs to be below 60c US) or else we are just priced out of the market. The same manufacturing cost in Australia compared to the US are much higher, it is only when the exchange rate is favourable to us that we are able to compete on the US market when we export from Australia to that market. At this point in time, all things considered, it would be MUCH cheaper to manufacture the same product in the US than it is to make it within Australia and export it.
