The closure has caused disruption to scheduled walks and activities for groups already on the island.
“There are about three or four groups already on the island in the middle of all the walks and the shutdown means they can’t do their walks and all their schedules are disrupted,” Cafe operator and treasurer of the local tourism association Stephen Sia told the ABC.
“It’s a busy time of the year leading up to Easter and there have been requests for refunds and all sorts of compensation.”
Myrtle rust, discovered on the island on February 3, has the potential to alter the ecology and affect the world heritage values of the island.
Infected sites have been identified in three additional locations, and necessary measures are being taken to manage this ecological threat.
Myrtle rust experts from the NSW Department of Planning and Environment and Department of Primary Industries will hold an information session on the island on Thursday, March 16.
In recent years the island has been plagued by rats, prompting a $16 million scheme from the government to eradicate the pests.
Unfortunately, the destructive fungus has also been found in New Zealand, on Mauao in Tauranga.
The invasive disease can impact pōhutukawa, rāta, and mānuka which are members of the myrtle family and found on Mauao.
Mauao Trust posted on its Facebook page yesterday that Myrtle Rust was “unfortunately now present on Mauao”.
