Hi Nibose,
I've recently found this e-shop in the Czech Republic, with a good range of OEM mechanical, electrical and trim/accessory parts for VW Group cars: Cars Equipment s.r.o.
Definitely worth a look through their website, and they have a good fast email response (but 9hrs behind Sydney DST) in English to any questions/requests for listed parts or even other parts not listed.
I've opened an account with them (they will provide non-VAT price for Aus buyers if requested) and bought some trim parts air mailed to me same day as purchased.
Normal air mail takes about 15-20 days to arrive in Aus, but express delivery in 5-7 days is an option at extra cost.
Mail cost details/options are available on website after you set up account and place items in cart.
