Nanophyllium australianum, also known as the Queensland leaf insect, is a species of leaf insect found in the Iron Range in Northern Queensland.

[1] Phyllium monteithei is the second species of Australian native leaf insect, other than Nanophyllium australianum.

In 2023, Minibeast wildlife received a donation of a female Nanophyllium australianum from the Iron Range.

Males appear black in colour, mimicking certain wasp species.
