rollzee said.. not sure if fone have a base in Australia?

Not anymore no. Even if they did, stick-on kite valves with tear-aid bases are not made by the kite manufacturer directly. The valve itself may come from the kite factory but it's a third party (such as FixMyKite USA or Dr Tuba) that buys or makes ''naked'' valves in bulk and thermo-welds them onto stick-on tear-aid bases.

It also depends on which valve(s) and which year/model of kite.

You can buy them directly from Dr Tuba in Slovenia : drtuba.eu/adhesive-valves

If you're lucky, Ryan aka The Sail Doctor thesaildoctor.com.au/ may have some in stock in Perth and post them to you. I believe he sources them from Dr Tuba.

You can also buy them from FixMyKite USA but probably more expensive compared to Dr. Tuba www.fixmykite.com/products.asp?cat=Self+Stick+Valves+by+FixMyKite.com

Expect to pay at least $30 AUD per valve delivered. If you have lots of valves to change it's sometimes the same cost or cheaper to replace all your bladders with pre-installed thermo-welded valves, which will last a long time and give you peace of mind. You can usually order an entire bladder set from Dr.Tuba for roughly $250-$350 AUD delivered to Australia depending on the kite size, number of struts and shipping speed.

Good Luck
