This Act amends the Rail Safety National Law and is the fourth amendment package to be considered by the South Australian Parliament. The first rail amendment package commenced on 1 July 2015, the second on 1 September 2016 and the third on 1 July 2017. This Act:

• extends the drug and alcohol provisions of the national law, which governs the requirement for a rail safety worker to submit to a drug screening test, oral fluid analysis or blood test or a combination of these.
• amends section 244 of the national law to provide an additional exception for the release of documents where lawfully provided for under the South Australian Freedom of Information Act 1991;
• allows the rail regulator to access the use of private sector auditing, as approved by the Transport and Infrastructure Council, for the purpose of auditing the rail regulator's annual financial statements;
• amends definitions in section 4 of 'level crossing' and 'rail or road crossing' and deletes the definition of 'railway crossing' to support consistency in the national law;
• creates penalties for public road managers who fail in their risk management duties at a road or rail crossing, consistent with the penalties for a rail infrastructure manager in section 107(1) of the national law for the same offences;
• gives the rail regulator the explicit ability to enter premises for drug and alcohol testing; and
• amends section 200 to substitute 'level crossing' instead of the deleted 'railway crossing'.
