Plywood gauge for ceilings.

We are renovating and going to put plywood 1200x 2400mm ply panels over the patchy tongue and groove wooden ceiling. (Original ceiling has been patched and has some gaps so we can't use it unfortunately.) Would we need to use 12mm ply or is 9 or 10mm OK. We were going to use paint clear metallex on reverse side as a precaution against possible borer and finish ceiling side with water based polyurethane for a lighter colour. Then we were going to use glue and a few staples or small nails to fix to ceiling. We are going to bevel edges and butt panels together. Any advice or suggestions greatly appreciated.
