What's the best way to buy vostok watches?

Hey, am planning to buy 2 vostok watches that I liked but am lil bit confused cause am from India and here we have to pay extra on customs(literally double and sometimes more than double too), I do have another option as well, I can get them shipped to my brother in Australia, but my question is will there be any extra customs duty too if I order from vostokinc.com or is there any better option as well then this! Please help.
