The Galgabba Point Landcare Group looks after an eight-hectare site on the old Pacific Highway.

A generator, hedge trimmers and other equipment were stolen in the most recent break-in two weeks ago.

Group co-ordinator Sharon McCarthy said while the group worked under the council and its Landcare Resource Centre, the council would not cover its insurance.

A council spokesperson said the resource centre had only been notified of one break-in in the past 12 months, but the council would investigate ways to prevent future incidents.
