I have several large Eucalyptus that need to be brought down behind my house and gardens.
They are heavily weighted, as well as side-leaning, in the same direction; which unfortunately is over a cliff with my house below. I have found that using 3 winches pulling the tree ~170 degrees away from the lean, without cutting a notch to fell the tree, to work well.
I use a 1 ton at the furthest point to pull the branches around nearly 90 degrees.
A second 2 ton is in the mid section to pull the larger central trunk as far as possible and to assist the smaller winch.
The final 3 ton is placed near the beginning of the bend in the trunk, about 20 meters above the base. This is to stabilize while I drive wedges into the cut and to help bring the largest portion of the tree trunk over its center of gravity.
I have found that making the back cut slant slightly downwards in the direction the winches are pulling to be helpful also.
I have not found much good information available for situations like this and would appreciate feedback from those who have worked with Eucalyptus and winches, or could direct me to some outside links online.

My concern is that by making a notch, I may weaken the tree prematurely and have it fall without control. The lumber is not valuable to me.

Man, this sounds scary! You need to post some pics. I have never cut a eucalyptus but I am guessing that could easily barber chair. Cutting a tree without using an undercut is never a good practice, an with a large tree can be very deadly. These are the best pics I could find showing a barber chair:
Be safe pardner!
