A vacuum chuck would also work.

I have these green Black wattle logs that I have just sawn into rough

I occurred to me after I turned the inside of the bowl out that I wont be
able to finish the bottom of a bowl.
Also should I leave the blanks to dry first or rough them down?

Mick, with 15mm sides, your options are limited, but if you are very
careful, you can turn a small recess in the foot to take a scroll chuck.
Turning from there on out would be done with a very light touch, as your
chuck will not have a lot to hold on to, but you should be able to do it.

Your other option would be a "jam chuck" and pressure from the tail stock,
with a pad to protect the bottom of the bowl - a piece of 1" stock would
do.

I do have a question, how are you turning the inside of the bowl.
