I find this a little odd on account of the fact the 0-50gm pricing is only available for overseas letters. The aust letters the lowest rate is 0-125g. So, in the interests of simplicity (and to err in favour of the merchant), the Austpost module ignores the 0-50gm possibility, and will use the <125gm rates as the *minimum* charge, which doesn't quite gel with what you have stated, so even I am a bit confused over this one.
Sorry Rod... I did state I was doing these calculations for postage from Australia to the US, however... to go into a bit more detail in regards to Australian rates, comparing the calculations with the Auspost site, I have the following item in my cart:

Items: 1 Weight: 400grams Amount: $12.00 Dims: 10cmx10cmx0.2cm

Which is calculating the postage rate through the Shipping Estimator:
Letter (Sml) $0.55

In the Auspost calculator I entered the following:
Size: 100mmx100mm Thickness: Less than 5mm Weight: 250-500g
Which returns the postage rate:
Large Letter $2.75

Which, checking and checking again, has all of my entered dimensions and weights falling within the parameters for them to calculate correctly.
I should make clear that any product weighing less than 250g with the same dimensions is showing as Small Letter through the Austpost calculator.

Now, for International Letters, from Australia to the US using the same product example:

Items: 1 Weight: 400grams Amount: $12.00 Dims: 10cmx10cmx0.2cm

Is calculating the postage rate through the Shipping Estimator:
Letter (Sml) $2.05

In the Auspost calculator I selected the following:
Over 250g and up to 500g

Which returns the postage rate:
Letter (Air Mail) $12.20

It appears to me that the Shipping Estimator is returning the min weight rate (up to 50g) of $2.05 regardless of what the product actually weighs. The same goes for Australia - the weight is not affecting the cost of the postage.

I've tried quite a few different dims and weights and keep having the same problem. For packages the weights and dimensions are calculating correctly, so either I'm entering something wrong or there's a problem here....

I hope this makes sense and thank you for your assistance.
