Airport security is a rigorous process, most passengers expect to be pat down, luggage checked and sometimes drug tests are routine.
However, don't be surprised if you are asked to show the content of your phone or laptop by Australian Border Force officers.
Melbourne based Molina Swarup Asthana is Principal of Swarup Asthana Lawyers.

Ms Asthana told SBS Hindi, "Like US, Australia does not have any legislation to protect from this so-called 'intrusion."
The Australian Border Force website says its officers are authorised to question travellers and examine goods if they suspect a person may be breaching immigration, customs, biosecurity, health and national security laws.
