Question: Have entry fees been waived at any Commonwealth National Parks?

Answer passage (source: Australia):
page_title: Leaving Australia
section_headers: Non-citizens
section_content: Due to the current COVID-19 situation in Australia, including state and
territory border restrictions, business closures and social distancing
requirements, international visitors are encouraged to return home when
possible to do so.
Temporary visa holders should be aware that if they wish to return to
Australia while COVID-19 restrictions are in place, they will generally need a
travel exemption. For more information about the Commissioner’s Exemption, see
Coming to Australia.

Reviewer feedback on this answer:
This answer is irrelevant to the question. This answer provides information on temporary visa holder and the recommendation for international visitors to return home. It does not provide any information on entry fees to Commonwealth National Parks.
This answer really doesn't talk about the parks asked about in the question.  I'm not sure that the question would be answered here.

fees and remain free to visitors.

Commonwealth National Parks by:

Providing temporary relief from licence fees and permit charges levied by the Director of National Parks for the period of 1 January 2020 to 31 March 2021.

page_title: Frequently Asked Questions
section_headers: Working holiday makers
I had to leave Australia and I couldn’t complete my specified work due to COVID-19. My visa is likely to cease before I can come back to Australia. Can the validity be extended?
section_content: It is not possible to extend the validity your WHM visa. If you wish to return
to Australia in the future, you will need to apply and meet the requirements
for an appropriate visa. Depending on your circumstances, you may not meet the
requirements for another WHM visa.

Reviewer feedback on this answer:
This answer is irrelevant to the question. This answer provides information on WHM visa in Australia and does not provide any information on entry fees waiver at Commonwealth National Parks as asked in the question.
This is talking about a VISA.  The question is asking about a fee on a park being waived.
