The local fire brigade and RFS were called to five outbreaks in grassland on Saturday.

They started at 4.15am on Rocky Hill, off the southern end of Memorial Drive, which burnt out about 100 square metres, NSW Fire and Rescue captain Tony brown said.

Police said another small outbreak at about 2.30pm, also on Rocky Hill, was quickly extinguished.

At 8.15pm, the Brigade was called to the old St John’s Orphanage in Mundy St where long grass near the Bourke St frontage was ablaze. Captain Brown said some 500sqm was burnt. One crew took a short time to extinguish it, while the RFS mopped up.

Captain Brown believed the fire was suspicious but said police would investigate. He told the Post that metre-high grass around the building was a concern.

Shortly after, at 9pm, the Brigade responded to an alarm at the nearby former Gill Waminda Aged Care Facility on Combermere St. There, someone had accessed the empty building and set alight curtains. There was minimal damage. Police are also investigating this matter.

Less than an hour later, crews doused another small grassfire in Finlay Rd near woolstores and Geissler Motors. It burnt about 20 square metres.
