Oh and there is a marked difference between locally made ply and the imported......
You can get different bond and finishes for different grade of ply.

The thing is, you buy ply from a place that specialises in it you will be able to order the grade and bond you want. Buy it from bunnings you get what you are given AND i doubt any of the staff will understand the difference between the glues and the materials.
