tfc always said if they didnt get enough interest they would not do aus sw project this year. so obviously not much interest. as for the 3.15% heartwood oil yield this is the average yield from a previous 14 yr old kunnunnarra sw plantation so it is achievable. the results from this trial are available on the net ....somewhere...i found it once. the main reults were average 3.15% with very high variability between trees.
