The Work Health and Safety Act 2011 (Cth) (WHS Act) states that a worker is a person who carries out work in any capacity for a person conducting a business or undertaking, including any of the following:
Others are also deemed to be workers including Australian Federal Police members (including the Commissioner and Deputy Commissioner) and Commonwealth statutory office holders.
If a person performs work, but does not do so for a person conducting a business or undertaking, the person is not a 'worker' for the purposes of the anti-bullying laws.
The Fair Work Commission has determined, for example, that a carer for a disabled person who is in receipt of a carer’s payment under the Social Security Act 1991 (Cth) is not a 'worker' because, even though the carer performs work, he or she does not do so for any business or undertaking. The Department of Human Services which pays the carer’s payment is not such a business or undertaking because the carer’s work is not performed for the Department.
See Fair Work Regulations 2009 (Cth) reg 6.08(2)
A member of the Defence Force is excluded from the definition of 'worker'.
No civil contract of any kind is created with the Crown or the Commonwealth as a result of:
See Fair Work Act ss.789FJ‒789FL
The following declarations may only be made with the approval of the Minister for Small and Family Business, the Workplace and Deregulation.
The Chief of the Defence Force may, by legislative instrument, declare that all or specified provisions of the ‘Workers bullied at work’ provisions do not apply in relation to a specified activity.
The Director-General of Security may, by legislative instrument, declare that all or specified provisions of the ‘Workers bullied at work’ provisions do not apply in relation to a person carrying out work for them.
The Director-General of the Australia Secret Intelligence Service may, by legislative instrument, declare that all or specified provisions of the ‘Workers bullied at work’ provisions do not apply in relation to a person carrying out work for them.
Nothing in the ‘Workers bullied at work’ provisions requires or permits a person to consider any action which could be prejudicial to Australia’s defence or national security, or an existing or future covert or international operation of the AFP.
Therefore, the Commission may be unable to make orders, or a person may be excused for contravening orders of the Commission, if doing so could reasonably be expected to compromise Australia’s defence or national security, or an operation of the AFP.
