"They can't detect downloaders so if I downloaded it but never shared it I wouldn't be concerned about it."
For those who do receive a letter from Dallas Buyers Club LLC allegeding they have illegally downloaded the film, it's important to seek legal advice and consider whether anyone else may have been using your network.
Mr Dalby said those who had an unsecured network or were free to giving out their wifi passwords may be able to use the "it wasn't me" defence.
"Most of the agreements state the account holder is responsible for the use of the account but there's no formal, legal obligation for customers to secure their WiFi," he told Fairfax.
"They can get to the router but they can't get down to the individual MAC (media access control) address of the devices but they're constantly modifying the technology and improving it."
A spokesman for Voltage Pictures (the parent company of Dallas Buyers Club LLC) has said there will be some demographics who would escape punishment.
These demographics included military pensioners, school students, low income earners and the mentally ill or disabled.
