"We've upgraded the lighting at the complex and we are investigating the installation of solar lighting in three locations which aren't well lit," Mr Carswell said.
"Our electrician is trialling equipment to ensure it is fit for purpose. Appropriate signage is currently being installed at entrances to the complex reminding people it is private property.
"We are also erecting a permanent fence to prevent pedestrian access to the lawn."
The idea of blocking vehicle and pedestrian access from Balance St with a gate was suggested but not supported by the majority of residents, Mr Carswell said.
Meanwhile, residents were advised to lock their homes at night.
Heathdene's Neighbourhood Support co-ordinator Lenny Ellwood said residents were generally happy with the measures council had offered.
"Nobody's going to want to walk in where there's lighting."
Mr Ellwood said there was a good community spirit at Heathdene and residents looked out for each other.
