Osman Shaptafaj entered the plea at Melbourne Magistrates’ Court this morning and will face a directions hearing at the Victorian Supreme Court later this month.
His daughter Lindita Musai and her husband Veton were shot at the Yarraville property on New Year’s Eve.
Police allege the couple, who had been married for one year, were ambushed on the veranda by Mr Shaptafaj.
Ms Musai, 25, was killed instantly. Mr Musai, 29, died from his injuries on New Year’s Day. Mr Shaptafaj, 55, was found a short distance away suffering gunshot wounds.
He was charged with two counts of murder at a bedside hearing in Melbourne’s The Alfred Hospital.
The young couple had just returned from a holiday to celebrate their first wedding anniversary.
They were laid to rest on January 4 at a funeral attended by hundreds of family and friends.
In a tribute on Facebook, Ms Musai’s brother, Arben Shaptafaj, described the family’s grief.
“Veton, my Best Friend, Brother, Golden Brother. We always felt it necessary to rank up our relationship to the next level as we progressed through life together. You were always the brother I never had and showed me how to breathe through the tough times in my life,” Mr Shaptafaj wrote.
“Always using your crazy sense of humour to be the centre of attention. You taught me to never give a damn what people think of you as long as you were happy.”
Paying tribute to his sister, Mr Shaptafaj described the 25-year-old as “the diamond in our family”.
“Lindita. My beautiful, loving, caring, sweet, kind and angelic sister. You were the diamond in our family, our princess,” he wrote.
A directions hearing will take place on May 29.
