Anyone around Albury/Wodonga?

Hey, I'm starting on quite a large project now, and I require a few materials to get it done.

The issue is, I'm not having much luck finding places around the Albury/Wodonga area.

What I'm looking for:

Styrofoam/Polystyrene in 1200x900 sheets
Some sort of transparent but frosted plastic. The stuff they use on milk bottles would be good, high density polyethylene? I think Styrene comes in frosted sheets also. Would also need 1200x900 sheets.

Does anyone know of any companies that carry this stuff?

I tried looking on clark rubbers website for some styrofoam, though it wasn't listed, and it appears they don't have a storefront in this area. I would be willing to drive a bit to a nearer town if they do have what I want. I suppose if there is no one local I'll have to grab some stuff on my next trip down to Melbourne, but I don't have to go there often.

Cheers,
Dan
