Q.Eucalyptus Tree
I have a eucalyptus tree, which would be about 20 high, but it is growing at an angle across the garden. I do not really want to cut it down, but it looks unsafe and is shading a large part of the grass. Any advice please?

If it is leaning severely, than it is likely a hazard and should be removed. But if it is only leaning slightly, you may want to consider a thinning pruning. At that height, there is not much you can do to correct the lean, but you can prune out some of the branches to open up the canopy and allow more light through to the plants below.
