Management actions
Continue weed control and habitat restoration work on Phillip Island, and establish effective quarantine protocols. If rats and cats can be controlled on Norfolk Island, it may be possible to establish a population there. Develop captive breeding protocols for the species so that the necessary procedures are in place if a translocation to another island is required in the future. Identify other islands where the Norfolk Island reptiles could be translocated to provide an insurance population.

The Lord Howe Island Biodiversity Management Plan covers the recovery needs of this species across its range outside of Norfolk Island. Possible future actions (such as captive breeding and translocation) may need to be undertaken in collaboration with the NSW Government as appropriate.

Recovery target
The recovery target is shown in Table 46.
