If people arrive in Melbourne, but their home is in Tasmania, they will have to quarantine in Melbourne, Mr Morrison said.
This will be enforced by the state and territory governments and will be supported by the Commonwealth while members of the Australian Defence Force will assist with compliance.
"We will be turning out the Defence Force to support compliance with these arrangements," Morrison says.
He says he's sure the ADF will perform compliance checks sensitively.
"We're in two fights, we're battling this thing on two fronts and both are important," he said.
"Both will take lives. Both will take livelihoods.
"It's incredibly important we continue to focus battling both enemies to Australia's way of life.
"We will be doing more to provide whatever support we can to support Australians and businesses during these difficult times.
"Every day someone's in a job for just another day is worth fighting for."
