Found two variants of acacia acuminata in kalgoorlie one at my work (narrow phyllode) and acacia burkitti near highway, will post pictures soon, question is; How much can be extracted out of burkitti phyllode's. > 1% ?, also could mineral turpentine be used for defatting or is naptha the go?

..interesting..cool..above 1% yes..do not use mineral turpentine!!..defat with similar non-polar solvent to extraction solent (i.e napatha) ..usually defatting of acacia phyllode not required (i.e near no fats come out)
.

If you're still in Kal would you be willing to meet up for a beer?
