How to show local shipping rates on my product/cart OR just cart page

[BAFC]

Hi,

I have local freight (shipping) enabled in my store. 

I have setup 3 x shipping rates that are postcode based/calculated

I want customers to be able to calculate their freight cost, either in the product and cart page OR just in the cart page. Either would be an improvement, so whichever is easiest. 

I have tried using apps, but they do not seem to accomodate local freight rates, just the more complex "General shipping rates" 

I only sell in one state in Australia, so I do not need the more general rates, just the local. 

I am using Dawn 11.0 theme.

Any help would be appreciated. 

Thanks
