..the earlier aussie acacias list was a guide to trees already used multiple times,
here is a complete (to date) list of AUSTRALIAN TRYPTAMINE & OTHER PSYCHOACTIVE ACACIAS

.
CURRENTLY UNDER INVESTIGATION DUE TO STRONG EVIDENCE
Acacia colei claimed DMT bark [ABC Radio National; several net reports]; needs confirmation, may be unsubstantiated.
Acacia concurrens (in research, bioassays/tryptamines reported 2012)
Acacia implexa (alkaloids known, but not identified)
Acacia macradenia (tryptamines reported net, confirmed by Spice Sailor DMT-Nexus 2012, await detail)
Acacia mangium (reported DMT, unconfirmed)
Acacia obliquifloila (in research)
Acacia penninervis (report of tryptamine-like extract/effects by cave paintings, dmt-nexus)
Acacia podalyriaefolia (tryptamine, phethylamine [White 1951]; all very low yeild results reported on net.
ALSO REPORTED PSYCHOACTIVE
Acacia beauverdiana
Acacia cuthbertsonii

..i still expect more tryptamine species to turn up over the next year or so...
