M Andresen is included in a list of over 100 Port recruits in the Port Melbourne Standard newspaper, 26 Feb 1916.

Possibly 752, Martin Julius ANDERSON, killed in action 24 April, 1918. The circular returned by his mother specifically nominated Beach Street, Port Melbourne as his place of birth. Victorian registrations just shown “Melbourne”, 1887, but have the spelling ANDERSEN, father not shown, mother Martina (Andersen). Commonwealth War Graves records show his father as Charles, there were several entries under this name in Port and South around the time of his birth. He enlisted from 1 Glover Street, South Melbourne with his mother as next of kin; a brother Charles also referenced, but there is no trace of a Charles born to Martina or Martine and the CWGC may have confused the names. Enquiries of his mother post-war brought the response “his father has not been seen of heard of for more than 20 years”
Thanks for your suggestion Brian. M Andresen is mentioned in the list of recent recruits in the Port Melbourne Standard edition of 26 February 1916. Martin Anderson enlisted 14 July 1915 so I don’t think they are the same person. So M Andresen remains a mystery.
