Kouroumblis was arrested at Rome's Leonardo Da Vinci Airport in September over the alleged slaying of Armstrong and Bartlett.
Dubbed the "Easey Street murders", police allege the friends were found dead with stab wounds in their home on Easey Street in Collingwood in Melbourne's inner north.
Bartlett's 16-month-old son was found unharmed in his cot.
The women went to school together at Benalla in Victoria's north, and their families said their deaths changed many lives "irrevocably".
Victoria Police Chief Commissioner Shane Patton has previously described the case as one of Victoria's "longest cold cases".
