Bark samples of 30 individual trees were collected from 6 potentially important Acacia species; A. falciformis, A. implexa, A. leucoclada, A. parramattensis, A. silvestris and A. trachyphloia in New South Wales and Australian Capital Territory. The bark samples from A. parramattensis gave the highest mean (50.2 percent of bark dry weight) of the extractives yield, while the lowest mean (21.9 percent) was obtained from barks of A. leucoclada. The two highest mean Stiasny values from A. falciformis (88.0 percent) and from A. parramattensis (82.8 percent) were not significantly different. The highest mean polyflavanoid content from A. parramattensis (41.7 percent) was significantly different from others. The bark quality of A. parramattensis for wood adhesives would be comparable to that of A. mearnsii provenances in New South Wales, Australia.
