Is this a 1948 case?

[Alfk]

Hi, I was looking into pursuing my situation through a maternal line, but can't really find examples.

GM born in Italy in 1924.
Moved to Australia in 1937, never naturalizes but then marries Australian GF in 1943.
Mother is born 1957.

Does my GM lose Italian citizenship automatically when she married and Australian pre-1948? If so, can this be challenged?

Thank you.

If your gm never naturalized on her own behalf or as a minor through her parents’ naturalization, she retained her Italian citizenship. Since your mother was born after 1948, this would go through the consulates.
