i'm actually confused as to what your issue is here...
this is what the australian cover for the game looks like.
however, it was not labelled as such because the OFLC (aussie classification system) logos are not present. instead, they were stickers placed over the plastic case to cover the PEGI logos.
i don't buy the 'spain flash' theory as i have a number of games sourced from the UK with the exact same 'pink flash'.
either way - the cover is european but as is the case with several other releases, the game/cover is identical (since both europe and australia are pal coded) in both regions.
if it is such an issue i can remove the cover, but i do believe over 100 people have found a use for it so far
