Another 27 trees have been hit by vandals in Wollongong less than a week after branches were sawn-off heritage tea trees at Belmore Basin.
Lord Mayor Gordon Bradbery has condemned the acts and is urging residents not to turn a blind eye to vegetation vandalism.
He's encouraging people to report it to Council or Police so the perpetrators can be brought to account.
"We need to put a stop to these acts of vandalism and to do this we need to work together as a community," he said.
24 established Casuarina trees that are part of an Ecologically Endangered Community have been illegally cut down in Holborn Park in Berkeley.
Council also confirmed that three newly planted Crepe Myrtles have been destroyed in MacCabe Park.
The Lord Mayor said was scathing of the destruction.
"Vandalised trees need to be replaced and are costly to plant and establish, however, the real costs are immeasurable.
"Tree vandalism robs future generations of the joys and pleasure that a great tree can provide - a climbing opportunity for children, or a shady space to stop and watch the world go by, or habitat for animals," he said.
The damaged coastal tea trees at Belmore Basin remain cordoned off.
Council said it will monitor them over the next six weeks in hope they regenerate before any decision on their future are made.
