A federal minister says he's sickened by reports Australian girls as young as nine are being taken overseas and forced to become child brides.

The Daily Telegraph reported on Tuesday at least 73 such cases had been reported to a NSW government hotline since mid-2014.

Treasurer and former immigration minister Scott Morrison said the issue sickened him and he urged anyone with information about the practice to contact police and child protection agencies.
