A Minto man accused of murdering his wife on Easter Sunday is due to face Campbelltown court next Tuesday.
Altaf Hossain was denied bail at a quick hearing in Parramatta on Monday morning.
The 49-year-old man is accused of stabbing wife Syeda, 33, to death in their Carruthers Street home on Sunday while their two children were asleep inside the house.
Mrs Hossain's body was discovered in the family's garage about 4am on April 22.
Mr Hossain was arrested at the Minto home on Sunday and taken to Campbelltown Police Station for questioning.
He was then transferred to Fairfield Hospital where he received treatment for a hand injury.
Mr Hossain later returned to the Campbelltown station and was charged with murder.
Bail was formally refused in Parramatta Bail Court on Monday, where he appeared via video link from the Amber Laurel Correctional Centre.
Police alleged in court that Mr Hossain had confessed to them about killing his wife.
Mr Hossain remains in custody ahead of a scheduled court appearance in Campbelltown court on Tuesday, April 30.
State Crime Command Homicide squad members are assisting Campbelltown detectives to piece together the events that lead to Mrs Hossain's death.
Officers established a crime scene at the Minto home which was forensically examined.
Police say the family has no history of domestic violence.
It is understood the two children - aged six and 10 - are now in the care of protective services.
The children were not harmed during Sunday's incident.
Family friend Zahir Bhuiyan told Nine News that he was shocked by the death.
"They are a good couple, a good family," he said.
"But we don't know what happens inside [the home]."
Carruthers Street neighbour Khadija Sarker said Mrs Hossain "doesn't deserve this death".
Another neighbour, Shamsul Huda, said Mrs Hossain was a "good mother".
Anyone with information about the case is urged to call Crime Stoppers on 1800 333 000.
