Spanish flu

Was the Spanish flu outbreak 1819 or 1919. There was definitely an outbreak in 1919. I understand some soldiers returning from the war brought it with them. Supposedly. My grandmother was pregnant with her first child and she cared for her parents during this time, They all caught it , husband included except for her. They all survived and she went on to have 5 more children. This was in country , Australia.
