Do I need to buy social security for my employees when doing business in Australia?

To do business in Australia, employees must pay endowment insurance. General enterprises pay 9% of employees' wages, while school teachers and government civil servants pay a higher proportion, about 12%. Unlike China's social security (employers and employees have to pay a certain percentage), Australia's old-age insurance only needs the boss to pay, and employees don't need to pay. Moreover, this part of the endowment insurance is not paid by the boss to the private insurance company. When employees reach retirement age, they can receive their own pension from insurance companies according to regulations.
