Yes.
Vehicles made by VAG (which include Audi, Skoda, Seat and Volkswagen) all need to use lubricants approved to a specific VW standard.
Previously, there were many VW standards which made it confusing for the motorist, so in 2004 they consolidated all the previous standards into one: 504.00/507.00.
Unfortunately, certain R5 TDI and V10 TDI engines can't use the new standard, so they are still required to use one of the older standards: 503.00/503.01/506.01. This applies if your Transporter has any of following engine codes: AXD, AXE or BLJ.
Since the introduction of 504.00/507.00, many lubricant manufacturers have not renewed their approvals for 503.00/503.01/506.01, drastically reducing choice. So to the best of my knowledge, this is what's left on the Australian market (not that there was much to begin with):
Castrol Edge Longlife II 0W-30
Castrol SLX Professional Longtec Longlife II 0W-30
Fuchs Titan Supersyn Longlife Plus 0W-30
Liqui Moly Synthoil Longtime Plus 0W-30
Motul Specific 506 01 506 00 503 00 0W-30
They are not commonly found on retail shelves, so you will need to make enquires to their sales department before you go out to purchase it.
You will also probably be better off buying in bulk (20 l) due to the price and the sump capacity (7.4 l without oil filter).
