First of I notice you have the scope pointing South very wrong by your compas reading.
Adelaide Magnetic Variation is aprox. 8° East
You have your scope compass pointing aprox 10° West,
so your scope is already pointing 18° West azimuth before you have started!
To correct line up the scope with the needle pointing 8° towards the West side of the compass!
which means the Magnetic Variation is now adjusted to aprox. 8° East.
Tip: adjust the centre compass so the correct needle setting lines up with a point on the knob.

Should make polar aligning a bit quicker.
The rest of your setup looks O.K.
