section_content: A person is a protected SCV New Zealand citizen holder if they fall within one
of the following groups:

in Australia on 26 February 2001
in Australia for 12 months in the 2 years immediately before this date
assessed as a protected SCV by Services Australia holder before 26 February 2004.

More information and advice on protected SCV holders can be found at the
Services Australia
website.

Reviewer feedback on this answer:
The information seems pertinent but the question is asking about why someone might need the visa, not whether or not they qualify for one.
This answer is irrelevant to the question. This is an information regarding protected SCV New Zealand citizen holder and does not provide any information on Covid-19 Pandemic event visa.

section_headers: Seasonal Workers
section_content: There are around 8,000 Seasonal and Pacific workers in Australia.
Seasonal and Pacific workers whose visas are expiring can apply for a further
visa to allow them to stay in Australia and support the agriculture sector,
subject to Labour Market testing. This is consistent with the principle that
visa settings should not displace job opportunities for Australians.
Seasonal Worker Program and Pacific Labour scheme workers, as well as Working
Holiday Makers and other visa holders working in agriculture, will be able to
extend their stay in Australia to support the agriculture sector:

Seasonal Worker Programme workers with visas due to expire will be able to apply for a Temporary Activity (subclass 408) visa in the Australian Government Endorsed Event (AGEE) stream.
Pacific Labour Scheme workers with visas due to expire can apply for a new Temporary Work (International Relations) (subclass 403) Pacific Labour scheme stream visa.

Workers currently in Australia under these programs will also be exempt from
the requirement to work for a single employer and be able to move between
approved employers, allowing flexibility and continued support for the
agriculture sector in meeting seasonal workforce demands.
Seasonal Worker Programme and Pacific Labour Scheme arrangements, including
those relating to employers, will be carried over to the new visa
arrangements, continuing the link with the agricultural sector.
Seasonal Worker Program and Pacific Labour scheme workers who cannot meet
their immediate living expenses can access up to $10,000 of their Australian
superannuation tax-free in the 2019-20 financial year.
More information about these temporary arrangements is available on the
Department’s website.

Reviewer feedback on this answer:
The information provided is thorough, and the opening paragraph gives an example of someone might need to apply for one of these visas, although all possible reasons aren't covered exhaustively.
This information does not provide any information on when a person should apply for Covid-19 Pandemic event visa as asked in the question. This information is explaining about people who are working under the Seasonal Worker Programme, Pacif Labour Scheme and Working Holiday Makers visa.

Working Holiday Maker visa holders
I have applied for my second or third WHM visa. Can I keep working while I am waiting for a decision on my application?
section_content: While your new application is being processed, a bridging visa will come into
effect which generally carries the same conditions as your previous visa,
including in relation to work rights. You and your employer can check Visa
Entitlement Verification Online (VEVO) at any time to confirm your work
rights.

Reviewer feedback on this answer:
The answer seems related to the question but only tangentially. It explains what happens after application, not why an application should be submitted in the first place.
This does not answer the question. The question is asking for information on when a person should apply a Covid-19 pandemic event visa and this information is about bridging visa and Visa Entitlement Verification Online.
