In Australia, the photo has to be signed by a guarantor [1] stating it's an accurate photo. However the guarantor can be any Australian passport holder who's known you for over a year and isn't an immediate relation/partner etc, so it's not particularly fraud proof.
The other part of that is that the original article mentions that often the morphing is not visible to humans, so its possible you can get a morphed image guaranteed just like any other.
Every time I've done this my guarantor hasn't scrutinized the photo, just glanced at it. And ditto when I've been a guarantor: "Hey al you sure you don't want to get a haircut before getting your passport?"
