What's 'cold'?
At -20dC and colder the clutch on my TDI got a tad stiffer, but moreso the shifter was quite hard to move initially (generally only after a few hundred feet or if warmed up was back to normal).
Being an automated manual, could see the same thing happening. Do you idle your car for a bit in the morning (even 30 seconds) or just take off? If not, I would sit for at least a minute on really cold days before taking off. Victoria normally isn't very cold but I guess this year is bringing different weather so don't know what it's like over there.
