Which of the following adopted a law on data protection and privacy for its citizens known as 'General Data Protection Regulation' in April 2016 and started implementation of it from 25th May, 2018?

Describes a law (Equalization Levy) introduced in 2016 with different clauses becoming effective on later, specific dates.

A student could use this as a pattern that laws can be enacted/introduced in one year (2016) and have staggered implementation dates, so check whether GDPR-like timing could occur in another country.

Notes a government policy adopted in 2016 and another law (Fugitive Economic Offenders Act) coming into force in April 2018 — showing adoption vs later in-force dates.

Use this as an example that national governments often adopt policies/laws in one year and bring them into force in a later year (e.g., 2018), so verify if Australia followed the same pattern for GDPR-like measures.

Shows that international treaty ratification (2006) and later domestic notification (March 2018) can be separated by years.

Apply the general rule that international/regulatory changes may require domestic notification/implementation at a later date; check whether Australia had to notify/implement an international-style data protection rule later than its original passage.

Gives a concrete example of a model law being brought out on a specific date (25 April 2017), illustrating governments publish model/central laws on precise calendar dates.

A student could compare official dates of model/central laws to determine plausibility of an April 2016 adoption date for a major regulation in another jurisdiction.

Explains that a legislature can enact laws to implement international agreements, indicating a legal mechanism for adopting externally-originated regulations domestically.

Use this mechanism to investigate whether Australia would 'adopt' an external regulation like the EU's GDPR or instead enact its own domestic law to implement equivalent standards.
