I think through sensible diplomacy and targeted aid the Australian government could stop the murderers in the people smuggling trade.
Sharing of knowledge when it comes to making vessels sea-worthy will only drive the price up for people smugglers. Make them pay and make it price prohibitive to those considering the option.
Our customs service has become a joke as highlighted by 4 corners.
But who is willing to stop it? Bob Carr? LOL

Many people who arrive with a passport overstay there visa whilst in Australia. But at least the government know who they are.
