Looking for Field Family, Bunting Street, Cairns, 1950

Can you help? If so, email Brian.

• Hello,
  
  My name is Brian Austin, I am trying to trace my Great Uncle's family who lived in Bunting Street in the 1950's.
  
  His name was William Field, born Custom House, West Ham, England in 1892, his wife was Genty. I know William passed away in 1955, and I believe from Ancestry researchers that there are 3 daughters still living, but not sure where, or of married names.
  If anybody has any info, or could point me in the right direction, or pass on this e mail, I would be very grateful
  
  Kind regards
  Brian
  
  ps My mother's maiden name was Mary Jackson, and sister Audrey Jackson if this helps (William's half brother, my Grandfather, was James Jackson, born Custom House, West Ham in 1903
