Sydney airwaves (radio and FTA tv) are simply flooded with vaccination adverts over the last month from many many sources.
I've had need to watch some catch up on Nine Now app (where you cant skip ads) and every second advert is for getting the jab - this week alone I've seen ads from: Feds, NSW Government, Channel 9, Construction Union, Pubs/Hoteliers Association, Tourism NSW, Celebrity Chefs (Matt Moran & Co) and others, all pushing the positive opening up benefits for the vaccinated.
Its actually at saturation point right now, if your anywhere that advertising is.
