Migration Minister Alex Hawke has extolled the virtues of immigration detention as he weighs the fate of a Tamil family seeking protection.
The family from Biloela in central Queensland are being held on Christmas Island as their case drags through the courts.
The federal government has spent more than $6 million keeping Priya, Nades and their two Australian-born daughters in detention for the past three years.
Mr Hawke refused to comment specifically on the family's case because he will eventually be the primary decision-maker, but spruiked the broader value of Australia's immigration detention regime.
"It is a costly but necessary exercise, the immigration detention network, and we work to make sure we have as few people as possible in immigration detention, that people do the right thing," he told ABC radio on Thursday.
"But where people do the wrong thing, they are asked to leave Australia.
"A temporary visa is a privilege and not a right, and so people who are invited to Australia on temporary visas are guests of Australia."
Priya and Nades came to Australia separately by boat in 2012 and 2013.
As their legal claims for protection went through the courts, the couple married and settled in Biloela in 2014, where they lived and worked for about three years.
The couple and their two daughters, Kopika and Tharunicaa, were taken from Biloela in 2018 and put into immigration detention.
The family remains on Christmas Island while their long-running court case slowly proceeds.
Home Affairs Minister Karen Andrews has indicated the family could be released into the community while their claims for protection go through the courts.
"In terms of other accommodation that may be available to them on Christmas Island, that's an ongoing discussion that I am having with our officials," she said on Wednesday.
"I will make a response in the not too distant future."
Ms Andrews was also asked whether she felt compassion for the Biloela family.
"I am a very compassionate person by nature. I will never walk away from that. But compassion takes many different forms," she said.
As the home affairs minister, Ms Andrews could intervene and grant the family protection, allowing them to return to their adopted home in central Queensland.
But she has been reluctant to step in while the legal case remains afoot.
"The matter is currently before the courts, so there is nothing I am prepared to say or do at this point in time that would either jeopardise the positions of the government or of the family concerned," Ms Andrews said.
"At this point, it is a wait and see what the results are through the court systems."
