"Under Immigration Minister Andrew Giles, the revocation rate was around 20 per cent. In other words, Giles was allowing around half the number of non-citizen criminals to stay in Australia as Dutton did. That was before Giles’ recent actions to cancel the visas of around 40 non-citizens whose visa cancellations were revoked since he was Minister as well as under previous ministers."
So Duttons own record directly counters your claim he will be tough on criminals, border protection and immigration policy.
