Australia's health chief Brendan Murphy says that COVID vaccines did prevent transmission in Australia (see 4:00 onwards).

Murphy's assertion suggests Australia's experience with the COVID vaccines has been different to the rest of the world, for example the experience in Singapore, where in an interview with Emma Connors published in the Australian Financial Review Australian  infectious disease expert Dale Fisher who now lives and works in Singapore said: 

The concept of herd immunity is that when enough people around you are vaccinated, you’re shielded. But when vaccinated people can actually transmit it, you are not shielded. There is no herd immunity.
