The Australian Maritime Safety Authority (AMSA) have announced exemptions they may use during the COVID-19 period:

Certificate Exemptions

Extension of time for certificate renewals

Due to the current social isolation restrictions and uncertainty caused by COVID-19, and to assist seafarers during this period, AMSA have extended the duration of all National Law certificates of competency.

If you have a certificate of competency (not suspended or revoked) that expires between 26 March 2020 and 1 October 2020, you have an extension of six months to renew your certificate. You must continue to comply with the conditions of the expired certificate.

QLD Update 6/04/2020:

Queensland’s government has restricted entry to the state, which applies at all points of entry to the State, whether by air, road, rail or sea. As of 12:01 am on Friday 3 April 2020, only Queensland residents and “exempt” persons will be allowed to enter the State.

Exempt people are those living outside of Queensland working in a variety of sectors. People involved in the transport of goods or freight by land, sea or air, are exempt. Maritime industry personnel who work in Queensland but who do not live in the state (for instance, crew on harbour tugs or dredgers) must apply for a “Border Entry Pass” to take advantage of the exemption.

When travelling it is also recommended that personnel carry a letter from their company highlighting the name of their employer, evidence that they are a maritime worker, evidence that they are entering Queensland to go directly to work, and evidence of the location of the work location.
