“Inquiries will be made by the relevant parties to ascertain the condition of the tree.”

"Given this time of year and given our severe weather we’re having, the heat and the winds, if you do go camping it’s likely to happen along the rivers, and people should make sure they’re aware of their surrounds when they’re walking through bushland,” he said.
