Freight is not included. Shade balls are delivered to a port, usually Sydney, and freight from there to your site is quoted separately. The exchange rate changes daily, so the final price is fixed when your order is confirmed.
How the estimate is worked out
Length × width gives the surface area in square metres. The area is multiplied by US$44 per square metre, then converted to Australian dollars at the current exchange rate. GST at 10% is added to give the total. Measurements in feet are converted to metres first.
What is not included
This is a supply price for the shade balls only. Freight from the delivery port to your site is quoted separately once we know where the shade balls are going, and installation is not included.
