Jagungal is a mountain near Kosciuzsko and 3 rivers flow from it , east south west. Near enough.  In 1025 after India attacked Java, many Tamils moved to Java and Tamil word jagangal means "communities".  Several Aboriginal tribes had ceremonies in the Snowy where jagungal means "table-top mountain" and manaro is "high plateau".

Shiva created the Himalaya rivers with wife Parvati.
