Got any links to the double-vax calls? Because that's plain idiotic and ignores the science. Even with the pfizer the studies are showing upto 12 weeks is optimal. (Couldn't find original study but here's a couple news articles
[Forbes] [Birmingham Uni])
OTOH while searching I found that Vic has reduced the AstraZenica interval to 6 weeks.
[Royal Aus College of GPs] in an attempt to balance getting people vaccinated vs increasing case numbers. I note the recommendation is only to shorten for those in COVID hot-spots, but government, clunky, etc.
That being said, the interval is still 6 weeks for Pfizer too - haven't reduced it to the manufacturer's initial 3-week recommendation.
