They were growing in an area dominated by eucalyptus (Southern Blue Gum), with no exotics nearby (but still possible). I have one more closeup to try uploading, an if it is still inconclusive I can get better photos next time.
Pedicels hard to see clearly yet do not appear pubescent nor rusty hairy (compared to glabrous or sparse hairs). Growth tip buds shown here pale brown (orangish) not rusty hairy (red-furry).
