Frangipanis are great! They grow really nicely in coastal environments. I first saw them as a kid on holidays at the coast. We bought a plant and tried to grow it at home but we lived in a hot and dry climate in inner Australia and so we struggled.
Growing them around the coast should be fine though. They are all over the Gold Coast in Queensland.
