That's what I found striking, there was something different about it and I couldnt pick it.
Thanks for spotting the obvious, now I feel better :)

Haven't seen that before! Is this a random mutation or a recognised variety? Or did this one just happen to perch directly under all the other magpies?

This is a quite common variation. Most of the magpies in my area (south of Canberra) are white backs. There are various zones splitting the forms east/west and north/south throughout the country. Quite a bit of research has also happened around this topic. There is even a recent PhD!

There are 3 main plumages of Magpies. The White-backed subspecies of Magpie is most common in southern Australia, with the regular Black-backed subspecies occurring throughout the rest of Australia and the Western subspecies occurring in Southwest Western Australia. The White-backed Magpie is at its northernmost occurrence in the ACT area so it is generally more common to see Black-backed Magpies locally.
