We are an Australian based company which ships items nationally and international usually within 48 hours of receiving your order. All items shipped internationally are sent express air freight unless otherwise instructed.
You can calculate shipping rates inside the shopping cart. After adding all the products you would like, navigate to the cart and click the ESTIMATE SHIPPING & TAX link and for Australia you need to select from ALL dropdowns i.e. Country, State, Suburb and Postcode for the quote system to work. (there is a small delay as it searches) For International you just need the Country to get a quote, more detail is required at Check out to complete order
Our shipping providers do not deliver to P.O. Boxes.
If you have issues calculating freight please get in touch, the most common reason is post code does not match suburb or you are entering a p.o box.
