Opposition Leader Bill Shorten said Labor might be willing to support the deportation of children who commit crimes.
Australia does not currently deport minors.
But the Joint Standing Committee on Migration is examining the screening process when people are given Australian visas and support services when they arrive in Australia.
They are also looking into whether their visa can be revoked if child migrants join gangs.
Shorten said there may be merit in changing the law.
"If any of these people are on visas and not Australian citizens, they should go home," he said. "Why are we letting them become Australian citizens? Sorry, it's just a red line."
