I am hoping you aren't feeding them to you chams after you feed them eucalyptus, I have a source and may be able to get it to you alive enough for the aussies? I can go collect some, it is literally 15 minutes away from me, but I am across the US. I have shipped plants before though... like fresh plants? anyway that's all I got sadly. They are everywhere in parks and hiking trails here and I have fed certain... phasmids them that I kept as pets not feeders. They are rrelatively ignored here except for trimming when they become an annoyance.
