Sending one kite from coast to coast to major cities will cost you around $30-$50 (depending on weight and size) using your own packaging with Australia Post standard postage (approx 5 to 10 business days). Express post (approx. 2-5 business days) would be about $40 to $60. Add $20 to $30 for remote areas.

If you don't have a box, you can get these bags at Bunnings for $3 www.bunnings.com.au/wrap-move-70lt-moving-bag_p0038777 perfect for sending a kite.

You can get slightly cheaper rates via Sendle with similar delivery timeframes but they have more size restrictions compared to Australia Post.

Even considering delays, Australia post remains reliable and one of the most affordable options atm

hope this helps
