Fines as high as €4,000 could be imposed on people who breach mandatory hotel quarantine.
The Cabinet is meeting this evening to pass the legislation required for the plan, which will see travellers from countries deemed as high-risk forced to undergo two weeks in a designated facility at their own expense.
Offenders can also be jailed for up to a month.
There are currently 20 countries on the list including Austria, Brazil and South Africa.
The hotel stay will be at the traveller's expense, with a fee of €2,000 touted, though this is still to be signed off.
