Question: Will travellers to Australia be quarantined?

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:
Answers only what is expected if already in the country
This does not answer the question. The question is asking for information on whether or not travelers to Australia will be quarantined. However, the answer provides information on the recommendation for international visitors to return home and what to do if temporary visa holders wish to return to Australia.

Quarantine for arriving travellers 
section_content: Since 29 March 2020, all travellers arriving in Australia by air or sea must
be isolated in mandatory quarantine accommodation for 14
days from their arrival, with
few exceptions. After mandatory quarantine, they can transit domestically and
travel home.
These requirements are managed and enforced by state and territory governments
with Australian Government support, including from the Australian Defence
Force and Australian Border Force.
Travellers are quarantined in the city they arrive in for 14 days, even if
they don’t normally live there or plan to travel elsewhere in Australia from
there.
Most quarantine accommodation is being managed by state and territory
governments. They will:

handle transport for travellers from their arrival point to their quarantine accommodation
manage quarantine arrangements at the accommodation facility

To find out more about the quarantine requirements in your state or territory,
or to ask about someone you know who has been quarantined, contact your state
or territory government health department.
The Chief Medical Officer can, in consultation with the Australian Health
Protection Principal Committee, declare a
Human Health Response Zone (HHRZ) to support quarantine and isolation
procedures. Mandatory quarantine arrangements are mostly being managed under
state and territory public health legislation.
