Can someone enlighten me on what the Australian TV broadcast PAL pixel
aspect ratio is?

(Not to be confused with the screen aspect ratio)

No such animal with an analog standard.

** Broadcast PAL is analogue - so pixels are not involved. The video
information bandwidth is about 4.5 MHz into which luminance and chrominance
signals are squeezed.

625 interlaced lines are used but about 50 are black.

This tends to be cause for debate - unlike NTSC pixels which are tall, PAL
pixels are wide. In the digital video world, a D1 PAL frame is 720x576, and
for a 4:3 picture, the pixel aspect ratio is therefore 1.067. However the
active picture is 702x576 which equates to 1.094, which is the basis for
MPEG-2 on DVDs.

** The OP asked for "PAL broadcast.... " - you are reading his mind by
relating that to digitisation of the signal.
