Help Find a WW2 American Soldier

Jill wrote to ask my help finding a WW2 American soldier. I am hoping that someone reading this query will be able to offer ideas or find Stanley! There are several men with this soldier's name in the WW2 database on Ancestry.com, and I cannot determine with certainty which might be the right one.

This soldier (Stanley Thompson) lost his Dog Tag in Australia. We know his next of kin was Mabel, but we don't know if she was his wife or mother or.... This will take a team effort I think to find information on him!

Here is Jill's information and a photo of the dog tag (ID tag) she found

I found one dog tag while fossicking around a WW11 site in the Northern Territory Australia. It is obviously in poor condition actually in two pieces.it is for a Stanley Thompson
