Employers have been warned of the serious nature of the penalties that can be imposed on them if they hire migrant workers in breach of their visa restrictions.
A spokesperson for the DIAC said: "We do have [an] immigration dob line set up where people in the community can provide that information if they're aware of illegal work activities".
Employers often hire skilled migrant workers to assist with their business operations - a process that can be made easier with the help of a migration lawyer.
However, business owners who take on foreign workers illegally can face harsh penalties, including fines and imprisonment.
This highlights the need to gain trusted advice from an immigration lawyer before starting the hiring process.
The DIAC has made a number of services available to employers wishing to know more about the details involved when contracting foreign employees.
In the case of current visa holders, firms can make use of the Visa Entitlement Verification Online (VEVO) facility to check the veracity of a person's right to work.
With the individual's permission, an Australian organisation may submit certain identification details to the DIAC through its website to gain the particular details of a person's entitlement to gain employment.
In Australia, businesses in the agricultural industry are able to make use of a number of avenues to gain access to semi-skilled international labour.
This is particularly useful to farmers that grow seasonal crops that require sudden increases in the amount of labour required to process the fresh produce.
