Answered my own question by luck. Drove past Mitchel Plastics in south Melbourne.
They cut me 2 sheets of 500x500 mm 4050 opaque perpspex espicially used as a diffuser. Guy in the place new a bit about light boxes and diffusing and reccomednded the right plastic. Which is the 4050 37% light transmission version
Cost me $20 for 2 pieces and $10 to cut it
