His wife Karthika Gnaneswaran says she doesn't know how she will manage without her husband and doesn’t want daughter Najomi to be without her father. She also expressed fears for her husband’s safety should he return to Sri Lanka.
The Tamil Refugee Council claims Mr Gnaneswaran was tortured by Sri Lankan security officers prior to his arrival in Australia because of his family's strong connections to rebel group Liberation Tigers of Tamil Eelam.
"I'm really worried about what could happen to him at the hands of the CID [the Criminal Investigation Department of the Sri Lanka Police] and army," Ms Gnaneswaran told SBS News on Monday at a protest outside the detention centre.
"I'm also scared about being separated from him."
"I'd like to request the government don't send my husband back, our child's future will be impacted and I don't know how we can live without him," she said.
"I don't want my child to grow up without the safety and protection of her father. She will always have my support but every daughter needs a father as well."
The couple arrived in Australia separately and were married in 2016 in a religious ceremony. Ms Gnaneswaran and her daughter were granted a temporary protection Safe Haven Enterprise Visa, but her husband wasn’t.
Tamil Refugee Council spokesperson Aran Mylvaganam said the couple received little legal advice and incorrectly applied for the protection visas as individuals as opposed to a single family unit.
"When they got married they should have been on the same application," said Mr Mylvaganam.
Lawyers representing Mr Gnaneswaran lodged an 11th-hour appeal to Minister for Home Affairs Peter Dutton's office on Sunday night.
"We are just hoping someone will convince the minister not to go ahead with the deportation," Mr Mylvaganam said.
SBS News has contacted the Department of Home Affairs for comment.
