Inspections in Fraser Island townships continue every May and November, with great work occurring with the volunteer groups and residents.

Look out for—Sisal hemp

There are still plants being brought over from the mainland seen without any known quarantine. Please think before bringing plants to the island to reduce the potential for spreading disease and pests.

We are hoping that we have tackled most of the large broad-leaved peppers in Happy Valley, but if anyone knows of any more please let us know. This also applies with the spotting of Easter Cassia and umbrella trees in Eurong.

This work could not be achieved without all FINIA associates’ assistance. Thank you.
