International shipping customers in these countries must pay a A$45 delivery charge, according to the Kathmandu website.
Across Europe the delivery charges range from 10 to 15 pounds.

"The expansion of our international delivery offer is one of a number of initiatives that we are rolling out which will assist in growing our business."
The retailer said it would continue to add to the country list over the coming months.
