Myrtle Rust
27 Dec 2011
Myrtle Rust is a recently-described fungus affecting Myrtaceae, which includes Eucalypts and Callistemons. It is present in SE Queensland and extending down the NSW seaboard. There is no known means of eradicating it at present. It produces bright-yellow lumps on plants, and is spread by spores. Its impact is potentially devastating to the Bush.
As a result, quarantine restrictions on travel of plant material and soil have been tightened (and rightly so - green snails, fire ants and cane toads haven't been stopped in their spread).
Please check with AQIS before you consider sending or transporting any plant material .
