This topic is about finding Sure Seal rings or tapes in Australia to help waterproof ostomy appliances, especially for swimming. The person is eager to swim for the first time this spring but is facing challenges with adhesion and is looking for solutions.

Here are some helpful insights and advice:

1. Many people find that if their ostomy appliance fits well, they don't need extra waterproof layers. You might want to explore "Sports and Ostomy" discussions for tips on swimming techniques and products like hardware-store tapes, support belts, or wetsuits that others have found useful.

2. If you're dealing with persistent adhesion issues:
- One creative solution is to make custom baseplates secured with a double elastic belt, which can last for months. The appliance is then attached to this baseplate.
- Hollister Adapt 7730 Medical Adhesive Spray has been praised for improving grip. Spraying it under the baseplate can prevent slipping, even with mucus buildup. It might be worth trying on regular flanges or Sure Seal rings.

3. Be aware that Hollister Adapt 7730 is being discontinued worldwide. Australian users have confirmed this, so consider:
- Purchasing any remaining stock, as it has a shelf life of about five years if stored in a cool place.
- Searching for alternative sprays or adhesives. A new forum thread is available to discuss potential replacements.

4. Some products, like barrier extenders, "pink tape," and appliances from Braun, Coloplast, Hollister, and Dansac, have been tested but found less secure for vigorous swimming.

5. If you can't find Sure Seal rings, consider:
- Trying waterproof tapes available at local hardware or chemist shops.
- Using a snug support belt or a lightweight wetsuit over the pouch for added security.
