Hi Bron,
There was a recent post on the Victorian Iris Society fb where someone in Rockhampton has "Puff the Magic" and "Taffeta Tantrum" growing well there

He also mentions that he grows "I'm Wicked" on someone else's post

Are your weather conditions similar to Rockhampton? If so, I can ask him what other irises grow well for him.
At the end of the bloom season I will have several clumps to divide and I am happy to send you some for the cost of postage if you are interested.
