According to the Workers and Safety code in Australia, all supervisors are required by the law to equip effective communication channels to their employees if they work under conditions that do not allow them to have average mobile phone communication. For most workers, this basically means the use of satellite phones however the law doesn't designate that the satellite phone as the only means they can replace standard telephone conversations. This code is specially meant to apply to workers under the OHS Act and this excludes people who are working by the federal government, who work in farms or ranches or those who are self-employed. This is generally because for self-employed individual, they will make sure that they have efficient communication means because they have to communicate with their suppliers. The code was therefore made to make sure that employees do not head out for days without having a means to communicate with other people.

The code was also created to be sure that if ever a supervisor has employed security guards to offer protective services to either lands or people, they must be prepared enough to respond to incidence calls or threats without much of a delay. This not only important but is now a requirement before any employer employed a security guard. All most all employers like better using a sat phone because it is more convenient in case of any catastrophes and communication will not be deterred by terrestrial connectivity that are primarily used for phones. In addition, these communications are known to broken on some occasions and this could be an excellent threat when a security guard cannot reply to the emergency situation simply because they cannot communicate or call for assistance. The occupational health and safety code generally focuses on an workers safety and well being but also doubles up as an additional safety measure for the supervisor.

According to the civil code, employers are essential to have the effective communication system especially when an employee is working alone. The law allows the employer to make a venture evaluation in order to check the appropriate communication system. This evaluation is only conducted once and it will only change if ever the working conditions also change. Hence, if the assessment shows that when making use of a satellite mobile phone is the most appropriate communication channel, then this will stay the same unless a more appropriate system comes up with time. The constitution also does not state that a supervisor is required to provide satellite phones or any other ways of connection to their employees if they make regular call-ins at pre-determined intervals to make sure the security of their workers. The call-in intervals will be based on the risk evaluation and will therefore be opposing for individual work situations. This may be at the beginning and end of a shift or every few hours if the working scenario carries more hazards. This constitution works best in far-off work places where there is a bigger chance of incidences and little means of communication which means that that workers may not be able to call in for assistance in case of an emergency.
