I have come across this plant at an air bnb I'm staying at on the Sunshine Coast in Queensland. I'd love to know what it is, and also if I could take a cutting?

"copper spoons" - Kalanchoe orgyalis.
Curious name…

Ask the owners of the Air BnB if it is okay to take a cutting. Standard plant etiquette wherever you are

Agree, it's never OK without permission.

Also, not all kalanchoe will root from cuttings. Best cuttings are tip cuttings from non-blooming stems.

Good luck. Let us know the results. That's a really cool plant.

I agree it looks like Copper Spoons (Kalanchoe orgyalis); other common names are Toareny, Cinnamon Bear and Shoe Leather Kalanchoe. Here's our database listing for the plant: Copper Spoons (Kalanchoe orgyalis)

I agree, before taking a cutting, it's always important and the polite thing to do, to ask permission of the property owner. Many property owners will allow it without hesitation but some do not want guests snipping their plants for any reason, which is understandable in some circumstances because if every guest decided to take a cutting or two of a plant they liked while on holiday/vacation, it could lead to a not so pretty landscape aesthetic, in very short time.

asking about the plant "so I can find one to buy" or " where did you get it" would be a natural invitation for the owner to offer a cutting.

Yes, I agree, that would be a winning strategy. Also know the species is available from several online vendors in Australia. It is easy enough to find, now that you know the name.
