After doing some digging around to see what cover is available, I found out that finally Westpac credit cards that include complimentary travel insurance, now include COVID cover.
From their website:
From 30 June 2022, selected COVID-19 cover is available in the International Travel Insurance coverage under the following sections:
1.1 Overseas Emergency Assistance
1.2 Overseas Emergency Medical
1.4 Medical Evacuation & Repatriation
2.1 Cancellation
3.1 Additional Expenses

You should post as a deal, both NAB and ANZ ones were and they helped a lot of people.
