Mr Sinadinovic's large family was among 300 mourners at a funeral service at Dapto on Saturday, held in the wake of his death in horrific circumstances at Unanderra on September 19.

Those gathered sobbed openly and laughed at turns as fond stories were told, only to serve as a reminder of the immense tragedy and loss of potential that had occurred.

Born on April 6, 1984, Mr Sinadinovic spent his early years at Bowral, raised by his mother Eila Tirronen.

He later moved to Farmborough Heights to live with his sister, Sandra Stankovski, and her family, husband Sasha and sons Jared and Jono.

In a heartfelt eulogy, Jared, 16, told mourners of the devastation his family felt at having lost their beloved "Azza".

"Nanny worked long hours to give Uncle the life they shared. Mum and Dad regarded Uncle Aaron like one of their sons and played a huge part in helping Nanny bring him up," he said.

"Although a big man, most would have thought him not to be the cuddly type, but Uncle loved nothing more than to cuddle his family. He would often say to us, 'Come on boys, come over and give big Uncle a cuddle'.

"He loved nothing more than to spend every chance he could with his close family and his fiancee Tania (Manzini) and her family ... The family sitting down to a meal was something Uncle really loved."

Childhood friends spoke of Mr Sinadinovic's friendly nature and sense of humour.

"There was never a dull moment when Aaron was around, he was such a character. He always had us in stitches ... such a good bloke," Ben Reekie said.

Brian Wyatt said the word always associated with Mr Sinadinovic, who stood at 198cm tall, was "big".

"Not just for his physical attributes, but for his big personality, his big sense of humour and most importantly his big heart.

"Azza had a strong love for life, his family and mates, but especially for the women in his life, his sister, his mum and his beautiful Tania."
