Murray Magpie (Grallina cyanoleuca)

At least that's what we call them in South Australia.  I do believe they are also called Magpie-Larks, which is a bit weird because they are not related to magpies or to larks.

Much smaller than your regular Australian magpie and shyer, too.  We've have a breeding pair around the place, but they scoot off as soon as they spot movement.

I used our cheapie long lens for this - it does a good job when the light is good.

Here's some more info for curious minds.

Magpie-larks are often seen in parks, gardens and streetscapes in built-up areas, but it is equally common in farmland and open areas of the bush. Its familiar call, sometimes rendered as peewee or peewit, has led to those renditions being used as colloquial names for the species, though in South Australia it is known as the ‘Murray Magpie’. It is often confiding in urban areas, but less so elsewhere. (I really don't know what that last sentence means).  Magpie-larks build robust nests made from mud and rootlets, which male birds sometimes defend surprisingly vigorously.

The name Magpie-lark is quite misleading, as the species has no link with either the magpies or the larks. However, the Magpie-lark is sometimes confused with the Australian Magpie, Cracticus tibicen. While both species are black and white, the Magpie-lark is noticeably smaller than the Australian Magpie.

The Magpie-lark is distinctively marked in black and white. The thin whitish bill and pale iris separate it from other similarly coloured species. The adult male Magpie-lark has a white eyebrow and black face, while the female has an all-white face with no white eyebrow. Young birds have a black forehead, a white eyebrow and a white throat. The Magpie-lark is often referred to as a Peewee or Pee Wee, after the sound of its distinctive calls.
