Backhousia myrtifolia, or grey myrtle, is as common as anything, especially in riverine temperate rainforest, or dry rainforest on this side of the divide. I have crushed many leaves, and while they do have a nice scent, it's not a cinnamon smell exactly. Still good for cooking though, but more savoury. There's a situation with a lot of the Backhousias where there are chemovars with different essential oil makeups. One type of lemon myrtle has citronella rather than citral and is inedible, same with aniseed myrtle. The best thing to do is follow your nose. All Backhousias, (in fact all myrtles, including eucalypts and lillipillis) have scented leaves due to oil glands, so it must be pretty old foliage for it not to have a scent. None of the myrtles are toxic enough to do you any damage whatsoever before the aromatic flavour gets too strong, but I probably wouldn't mess around with Rhodomyrtus macrocarpa until the blindness-causing factor in this is identified. It probably doesn't have pleasantly scented leaves anyway.
