Very close mate! The insert is referred to as a privy. Many of the years were minted with these in addition to the standard design. What's more, there are multiple different privy designs per year and per denomination making them somewhat collectible.
The 1/10 0z silver kangaroo for 2013 came with a Chinese privy for example. The 1 oz also came with an F15 privy. There's quite a comprehensive list published by the Perth Mint here.
