eucalyptus

Hi all, I am trying to identify a Eucalypt growing in my backyard in Victoria, Australia. It is at a height where it would just hit our house if it fell so I'm trying to understand whether it is fast growing and at risk of falling to assess whether it should be cut down. Thanks!

I have finally joined Arboristsite.com!!! I am looking for some information on identifying this eucalyptus tree that is common in California. I know it’s not a blue gum, or a red ironbark. I think it is a grey ironbark, but I am not certain. Can anyone help me identify this tree?
