The topic at hand is about finding an alternative vent for ostomy pouches in Australia. The person is searching for a small, plastic "pop-up" vent that can be attached to the upper rear of an ostomy pouch. This vent would be used when the built-in charcoal filter gets blocked, which often happens after flushing the pouch. They are curious if such a vent is available and where it can be purchased in Australia.

Here are some insights and advice gathered from discussions:

1. The person found a supplier for these vents, but they cost about AUD 8.00 each, plus postage. They feel this is too expensive and are considering sticking with their current method instead.

2. Experiences with these clip-in vents vary. Some people like them, but many find them ineffective because even a small amount of output can block them.

3. One user who practices irrigation mentioned they can use the same pouch for several days without any output, which helps keep the vents clear. However, for regular use, these vents might not be very practical.

4. It might be a good idea to request free samples before making a purchase. This way, you can test their effectiveness and see if they are worth the cost.
