Anyone want one at their place? There are different covers available - clear, canopy and mosquito net.
Welcome to the Bunnings Workshop community @Bellcat. It's fantastic to have you join us and many thanks for your question.
It appears @Alicia posted this image quite some time ago. They are not a Bunnings product and I don't personally know where they would be from. Perhaps some of our other members might have an idea.
If you were interested in constructing something like this I trust our helpful members might be able to provide some solutions. I'm thinking you could use conduit to replicate a similar design.
We look forward to hearing about the projects you have going on around your house and garden and would encourage you to let us know if you ever need assistance with them or would like to share. I trust you'll find loads of inspiration within the community as our amazing members are contributing their projects here every day.
