I won't go into the deliberations an auditor probably makes on what is a review opinion, but the 25th of February was a different world:

- Covid-19 cases were about 4% of what they are today, the bulk in China and Korea, and the US had only 57 recorded cases, less than 0.01% of today https://www.worldometers.info/coronavirus/
- the football game that started the super spread in Italy and Spain had only been held six days ago and no one was even aware of what it had caused at that point https://www.theguardian.com/world/2020/mar/24/bergamo-mayor-says-football-match-escalated-coronavirus-infections-italian-province
- weekly air flight traffic numbers weren't far off their normal level other than in China and Korea https://www.visualcapitalist.com/global-flight-capacity-coronavirus/
- the S&P 500 and ASX 200 were barely off all-time highs

Six weeks ago, but a lifetime away

I'd also caution against a lawsuit of the auditors for the loss of frequent flyer points. The audit opinion is under the Corporations Law about the financial statements, not a guarantee about the viability of some points accrued under a loyalty scheme. You'd be better off redeeming them now for whatever you can and getting some value out of them, rather than losing them and then spending actual dollars on a fruitless lawsuit. Lots of chatter about that on the Australian Frequent Flyer forums.
