Well, 3TB HDDs are AUD$145 or so, not sure what postage would come to.
At 4K uncompressed it is about 3TB per reel, I have yet to convert to OpenEXR but it is usually about half that size. If I drop it to 14bpp then it will take up less space.
At 2K, which is really enough for Super8 I can probably get the entire film onto a single 3TB drive at 10bpp.
