Two children who died in a car fire in Perth's southern suburbs have been remembered as "shining stars" as their shattered father returned home to try make sense of what happened.
Tributes have flowed in for siblings Abiyah and Aiden Selvan, who perished in the fire alongside their mother Selvamma Doreswamy in Coogee on Monday.
Selvan Govindhan Vairavan was on a surprise journey to Philadelphia to see his brother when he learnt his children and wife had died in tragic circumstances.
Abraham Thavamani, the pastor at the Tsaraph Tabernacle church the family attended in Canning Vale, said Mr Govindhan Vairavan was still in "shock" upon returning to Perth.
"I had an opportunity to speak with Selvan last night and spent the morning with him," Pastor Thavamani said.
"He's absolutely shattered, obviously everyone can understand, just like any of us."
"He's still looking for answers … we don't know [why]."
Pastor Thavamani said the church "will be by his side" as he grieves the loss of his wife and children.
"His pain is beyond words. His love for you both was to the skies.
"It is a time of pain and shock and the grievance of everyone, of the family, the friends and the near and dear ones is beyond words.
"It's a time I don't know the answers to what has happened."
Abiya's smile 'shone from afar'
Pastor Thavamani remembered Selvamma and Selvan's two children, Abiyah, 10, and Aiden, eight, as "shining stars" and "little darlings".
"They are like shining stars and they shared joy and love wherever they go," he said.
Abiya was remembered as a "beacon of light" and as having a smile that shone from afar.
"You always carried yourself so elegantly, young woman.
"You have been plucked out of our lives, sweet little angel."
Aiden was 'full of life and energy'
He described Aiden as "Mr Cool" whose gentle smile stole people's hearts.
"Just like your sister, you were always ready to help everyone. You were fun to be around.
"The way you came up with dialogues off the cuff in the Sunday school skits were amazing.
"A little man of few words but full of life and energy."
Mother remembered as 'compassionate'
Selvamma Doreswamy, or Selvi as she was known, worked as a nurse at Fiona Stanley Hospital.
"She was a lovely lady who cared for her children," Pastor Thavamani said.
"You would defend your children at all times. You loved your husband and you were the crown of his life."
Pastor Thavamani said the close-knit church community was "equally broken".
The pastor said a family had stayed with Ms Doreswamy and her children on Sunday night.
"And even they couldn't see anything," he said.
"We didn't see it coming, none of us."
The two children were born in the United Kingdom before the family relocated to Melbourne and finally found their home in Perth.
The police investigation is continuing but they do not believe anyone else was involved in the deaths.
