I have a Pelican-style hard case (no idea of the make - but it's not Pelican) for sale. Internal dimensions 390 x 320 x 120mm. I got this with a camera I bought here but have no use for it. Good condition. The picture shows foam removed as I received it, but I've since filled it up with more foam so it can be re-plucked for whatever shape you have. Bright yellow so you can find it in the dark.
Outback NSW. Due to the size, I would expect postage to Alexandra Hills would likely be $18.95 based on it fitting in an extra-large pre-paid satchel. I don't think it would fit in the large one.
