AusBonsai

Just got this guy during a meeting of our local bonsai club, another member was clearing out few trees and I snapped it up quick smart!
I plan/want to flat cut at the area of reverse taper-question is when's the time to do this? I live in western Sydney and temps can be unpredictable. It can be in full sun or shade or any combination? Thoughts/comments appreciated:

you can chop into it now. Olives are tough as nails.

Good Luck as I have never been able to get olives to strike from flat cuts or large cuttings

Dunno why

No advise from me other than wait for Olivecrazy to post an opinion!

I don't even own an olive!

Your Olive shows the classic 'Onion Bulb' trait, common with this variety, unfortunately. I had dug a heap of good looking olives only to find they were Onions. On advice, they just ended up being another attempt to rid Adelaide of this weed pest. Olivecrazy will probably be more up to date with the information obtained about these things, I dug my last SA Olive in around 1998 or so. But my recollection was that the upper knob was not a part of the lignotuber and as such were difficult to get roots to shoot if cut and planted. One possible way around this might be to plant the tree deeply in a pot after damaging the bark where you require the roots. I have seen Olives layer themselves where braches touch the ground so this is a possibility. Only other suggestion in your case might be to allow any and all shoots that grow from the 'waisted' area to grow and develope in order to 'fill in' the area, removing them once they have done their job, slow option tho' .
