I think to have any understanding of the uptake in RAT you simply need to look at UK and US where Vax rates for 18+ have been well and truly above the 70% mark double jab for a while now. They are both seeing rising infection rates amongst the vaccinated populations (though, not currently transpiring into hospitalisations and deaths which is good) and this is feeding the continued demand for antigen tests from the consumer.

IMO - I see it playing out in Australia that we will be getting daily infections into the several thousands per state once we open up at 70-80%, and given we have had the fear of covid instilled in us for over 24+ months now. The stigma with being positive with the virus will not disappear over night, but will be around for many months to come. So, even fully vaccinated persons will still be wanting access to these tests just as though they want access to their daily morning coffee.

We've got 3-4 quarters of positive impact from COVID sales ahead IMO
