We contribute to a number of employee retirement plans for the benefit of our employees. Details of the main plans are as follows:

All Australian employees, after serving a qualifying period, are entitled to benefits on retirement, disability or death. Employees may contribute additional funds to the plans. We contribute to the plans at the rate of approximately 9.5% of the salaries of all Australian employees. Our total contributions to the plans for the years ended June 30, 2018, 2017 and 2016, were $10.5 million, $9.9 million and $9.1 million, respectively.

Company contributions to this plan are based on a percentage of employee contributions to a maximum of 4.0% of the employee’s salary. Our total contributions to the plan were $5.0 million, $4.3 million and $3.3 million in fiscal 2018, 2017 and 2016, respectively.
