Australian Medal Engravings
Australian WW2 Medals had the Service Number, Initials and Surname engraved onto them.
The different States had a letter before an X in front of the Number,for example;
QX1234 for Queensland,
NX1234 for New South Wales
VX1234 for Victoria
SX1234 for South Australia
WX1234 for Western Australia
TX1234 for Tasmania
There were two armies Militia and AIF. Both AIF and Militia Army numbers had the prefix indicating the state of enlistment.
The X was for the Australian Imperial Forces,if there is no X then it belonged to a Militia member.
Here is an example of the engravings on 2 of my Grandfathers Medals,
