What do the prefixes "CSC RAN" on Royal Australian Navy Officers titles mean?

Question

For instance, their title would be Rank-Full Name-CSC RAN

eg.CAPT Sven Svenson CSC RAN

RAN probably stands for Royal Australian Navy, but how do they acquire the prefix and what does CSC mean?

Answer 1

Conspicuous Service Cross.

It's an award the RAN gives out for outstanding service, not necessarily in wartime.
