an unusual eucalypt in an unusual location
These are Rusty Gums (Angophora costata subsp costata)
Angophora are unusual eucalypts in having (small) petals - most eucalypts have a bud cap instead.
The location - Blackbraes National Park in north Queensland - is an outlier from the species' main range by a distance of 1,500 km. Goodness knows how they got there.
