Hey Guys,
I'm in here as well, just sneaking more around in the Kombi club forum.
Indeed, I got a good source from a reliable dealer in Germany for factory style Decouplers at a price of EUR 599 incl. 19% GST (which we are normally able to deduct from the price). The last ones I got in were incl. shipping around AUD $950 at current exchange rate (complete set with hoses, vacuum switch, bulb for the dashboard etc.) + shipping costs for the core to/within Germany + core charge AUD $ 350 (which I offer to collect in Australia, so no Bank transfer charge will accrue for transferring it to/from Germany). At the current exchange rate, you will just stay below the AUD $ 1000 mark which saves you 10% import duty.
Regarding the exchange housing, that's a bit of a difficult point:
I know Alex since a while so we came up with an agreement to your benefit. I have got two spare nosecones in Germany which I'll give to Alex as exchange so he can assemble new decoupler sets. Which means, I actually take responsibility for collection of the core charge and your old housing (which has to be in good order, clean (!!!) and no cracks or missing parts!) which either has to be send direct to Germany (approx. AUD $ 135) or I may can offer to take it with me as travel back home at least once a year (which will cost you than maybe AUD $ 50 in total). However, availability of the option that I take it back home is limited to 2-3 per year and also on how far away my next trip is. Again "Worst case" you have to send it direct to Alex.
If you are interested, please send me a mail with your contact details to kleinersyncro(at)yahoo.com and I'll fill you in with further information
Cheers Arne
PS: I don't make money with this deal nor do I gain any benefit or advantages for myself!
