Emmauel Antonios Cassimatis moved to Australia

I have the great need to find out more information regarding my grandfather who arrived in Australia on 8th April 1914 at the age of 14. Emmauel Antonios Cassimatis (Cassum) lived his life in a small town in country NSW called Ardlethen where he ran and owned the local cafe. He came to Australia with a cousin, while his parents remained in Kythera. Emmauel was born in January 1899. What I need to know is which town in Kythera he was from and the name of his parents. Hoping some one can help me with this - it would be of great assistence. Thank you.
