These visitors still seem to be getting lost.
I suppose it is good practice for the SES, Police and ADF to try and find them. So there may be some benefit to our emergency services.
A cost benefit analysis needs to be done and a fee levied on all incoming visitors which is reimbursed when they leave the country, not having been "lost" in the interim.
In the meantime, let us hope this young lad is found alive and well.
