Most of the trees already on our property when we moved here are E. Leucoxylon, the S.A. Blue Gum, but this one may be a Camaldulensis,
or River Red Gum. We have no idea of the age, but one featured on Wikipedia that looks just like ours is said to be 700 years of age.
Ours grow near our front gate and there is often a koala having a sleep during the
day. People have stopped their car to take photos many times.
