While workplace inductions are not required in all industries and all workplaces, every single employer in Australia has a legal obligation to provide employees with adequate instruction and supervision.
Furthermore, inductions are mandatory in others such as construction, where two forms of Occupational Health and Safety (OHS) induction are required (construction induction training and a site induction).
Such industries usually also require employers to provide evidence that this induction has taken place.
Regardless of whether or not you are required to provide employees (or volunteers and visitors in some cases) with a formal induction, there are many reasons why you absolutely should provide an induction for every new employee.
They are outlined within this article and clearly show why the time and effort required to create an induction program are well worth it, for both the employer and the new employee.
