The body of a missing Queensland woman has been discovered in a small village in Bangladesh, two months after she first disappeared. 

Her estranged husband, an Australian-Bangladeshi citizen who was in Bangladesh at the time, returned to Australia a week after she was reported missing.

Mother-of-five Rehana Parvin travelled to her home country of Bangladesh with her teenage daughter on June 6.

Md Ashraful Alam, Senior Assistant Superintendent of Police (Dohar Circle, Dhaka), told the ABC that Ms Parvin's mother Airin Akhter officially reported the 38-year-old missing to Nawabganji police on July 3. 

While no charges have been laid, Mr Alam said Ms Akhter accused four people known to her daughter of abducting her, and alleged one of these people was her son-in-law Awlad Hossain

"On the 8th of September, [Rehana's] mother officially lodged a case against four people [alleging] they had kidnapped her and she was missing," Mr Alam said.

Bangladeshi authorities have applied for a warrant for Mr Hossain's arrest and have since identified a fifth person as part of the investigation.

Mr Alam said two people confessed to having knowledge of Ms Parvin's disappearance and have been arrested. They are Mr Hossain's sister, Papia Akhter, and Amzad Hossain, a man from the village where Ms Parvin grew up, according to police.

"We have found these two people arrested by police … were involved in this murder of this victim, and we are trying to arrest other people," he said.

"After completing our proper investigation, we will provide the charge sheet to the court … this is according to the law of our country."

Months-long disappearance flew under the radar in Australia

Ms Parvin's body was found on September 12 in a village in Ashulia, buried in the yard of Ms Akhter's property next to the septic tank.

Police have recovered Ms Parvin's body, and a post-mortem examination will take place at Salimullah Medical College Hospital Morgue.

Mr Alam said Ms Parvin's husband returned to Australia on July 13 having arrived in Bangladesh on June 29.

The ABC does not suggest that Mr Hossain had any involvement in his wife's death; only that Bangladeshi police have applied for an arrest warrant. 

Ms Parvin and Mr Hossain lived in Australia for almost 20 years, spending time in Brisbane and regional Queensland. 

After marrying in Bangladesh, the pair moved to Australia where they settled permanently and obtained citizenship.

But despite her months-long disappearance, Ms Parvin's case has received no media coverage in Australia. 

The family mostly kept to themselves and did not have substantial ties with the Bangladeshi community, the ABC understands.

The ABC can reveal Ms Parvin co-owned three properties with her husband, Mr Hossain, in Queensland's Western Downs region. One of the properties had 16 hectares and a modest home, while the others held substantial land.

A fourth property in the region with 14.6 hectares has Ms Parvin's name on the title. She also owned property in Bangladesh.

Mr Hossain, 48, also owned a property in Redbank Plains in Ipswich, a property search revealed.

Federal police say investigation is ongoing

A Queensland Police spokesperson said that prior to the discovery of Ms Parvin's body, the AFP had carriage of the missing person investigation. 

An AFP spokesperson said it had "received a report from the Queensland Police Service regarding a missing person report about an Australian citizen overseas".

"The AFP is liaising with international partners and the Bangladeshi authorities regarding this matter," they said.

"As this is an ongoing investigation the AFP has no further comment."

A Department of Foreign Affairs and Trade spokesperson said it was "providing consular assistance to the family of an Australian woman reported missing in Bangladesh".

Mr Alam said Bangladeshi police had worked extremely hard to investigate the matter.

"[Rehana] has very small kids. They were looking for their mother ... and deprived of [her] love," Mr Alam said.

"The Bangladeshi police were very concerned and worked hard … we tried our best to give justice to the family."

Mother demands 'justice'

Local media reported Ms Akhter told a press conference she "worked hard to educate" her daughter "and send her to Australia where she became a citizen".

"My daughter earned and acquired property in Australia … two months later, the police have found her remains. I demand justice and the execution of those responsible." 

Dr Jishu Das Gupta, a Bangladesh community leader in Queensland, extended his "heartfelt condolences" to Ms Parvin and her family.

"This is a tragic and unacceptable situation."

A spokesperson for the Coroners Court of Queensland said, "the scope of any potential investigation, including coordination with other jurisdictions, is yet to be determined given the death occurred overseas".

"As such, the CCQ is unable to provide any further information at this time."

Mr Hossain declined to comment.
