I am not super familiar with AU sizes, but based on the size chart it seems an AU size 8 is the equivalent to a US size 4. If this sounds right to you, I would recommend that you size up one size from your usual on this jacket, and I would personally recommend that you order a size 6.

@MsKate89 if you mean the Vegan Leather Jacket I got a size 4, which is one size up from my usual. It is an amazing piece!
