Are you all aware of green tree ants' Oecophylla smaragdina good moderation uses in flavouring up-market foods and drinks? – notable example: https://www.seven-seasons.com.au/product/green-ant-gin-700-ml/ .
More generally here, we eat a few green tree ants at times.
Please upload the other sighting we referred to in private messaging, I will confirm that sighting's identification and then confirm this sighting's identification.
Much respect for Kevin @plants and no division thereof - his correct awesome long experience–based suggestion for you to check local gardens' exotic species. Equally your own correct local site specific knowledge based suggestion that this sapling grows in a bush context and way. Hence suggesting a local indigenous species. We need respect for and love for diverse plurality of experiences–based points of view – i do not like the mostly pale–male authoritarian figure heads who have caused so much damage (topical across our shared planet Earth at this time) and evidences (facts) matter a lot – We all know the saying: We are all entitled to our own opinions, yet none of us have any entitlement to make up false facts –really just more mere opinions (again so topical re: one of the worst in history psychological projectioners, hypocrits, accusing everybody else of fake news but in reality, in actual facts, in many evidences, amongst the worst perpetrators of what he has so often accussed other people of doing. ).
