The Osborne family has lived in the supported-housing flat for 25 years and have put in requests with both Orange City Council and NSW Land and Housing Corporation, formally FACS, to have the bush removed.

Miss Osborne said the 30-foot long and 15-foot high blackberry bush is a risk to her three-year-old granddaughter who lives at the house.

"It has taken over three sheds and demolished two of them," she said.

"I want my granddaughter to be able to play in the backyard without being injured."

Orange City Council's community relations Nick Redmond said council only has a role to deal with weeds when they are on privately-owned land.

"Staff have the authority to ask the resident to remove the blackberries growing on their land, and if nothing is done, enter the land to remove the weeds and then bill the resident to cover the cost of the work," he said.

"This power to deal with priority weeds doesn't apply to land owned by another tier of government such as public housing properties."

Miss Osborne said she has put in 40-50 to calls to NSW Land and Housing Corporation, the government body responsible for public housing.

"We were told in October they would send someone from maintenance to look at it," she said.

"We're still waiting."

A spokesperson for the Land and Housing Corporation said the maintenance of the yard is the tenant's responsibility.

The lease agreement state's it is a tenants responsibility to "clean and maintain your property to a reasonable standard, including the gardens, and ensure that no damage is done.

Following enquiries by the Central Western Daily, the spokesperson said they would have the bush removed.

"Whilst there was no record of the blackberry bush being present on the property at the start of the tenancy, LAHC will arrange for a maintenance contractor to prepare a scope for the removal of the blackberry bush to ensure that no damage is caused," the spokesperson said.
