A 58-year-old man has been charged with murder after his 52-year-old partner was found dead at a home at Ipswich, west of Brisbane, on Monday night.
Emergency services said the body of the woman was discovered inside a property at Mountain Bell Lane in Springfield Lakes just after 10:00pm.
It is understood she suffered fatal wounds to her neck.
The man was arrested at the scene and taken into custody.
Detective Inspector David Briese said the pair were in a relationship and had just returned from a trip overseas.
"It appears that they had been away from the country for a period of time, at least a month, in South-East Asia and had only returned yesterday afternoon," he said.
Police said the pair were originally from South-East Asia but are permanent Australian residents, having lived in the country for more than a decade.
Detective Inspector Briese said family members, friends and neighbours had been spoken to as part of police inquiries, but anyone who knows the couple is urged to come forward.
"If they're aware of any issues, anything that's occurred recently or in the past that's happened between them, we'd be asking them to contact us," he said.
"We don't believe the public have anything to fear as a result of this incident."
The property will remain a crime scene as investigations continue.
"We have forensics and scenes of crime officers at the address under a crime scene warrant and we believe everything we needed to find we have," Detective Inspector Briese said.
The man is due to appear in the Ipswich Magistrates Court on Wednesday morning.
