Trying to find out how he arrived in Tasmania and from where?
Thanks
Where did you source Walter's place and year of death?There is no death for a Walter 
COLLINS in 
1922 in Brunswick, Vic.  The 1922 death is for a Walter 
COLLINS who was married to a Margaret 
MURRAY and according to his obituary, lived in the Geelong district for most of his life.  This Walter is interred in the adjacent grave to his wife at the Geelong Cemetery.  This is possibly his arrival in Geelong.

Did your Walter 
COLLINS in Tasmania spend time in gaol?
Seven days in gaol for refusing to pay a fine for assault.  Surely it's your man as Nathan  
HETHERINGTON was present.
