On the Australia Government HCV site they say differently. Most references and my doctor does too. Sharing needles is the big no no, but sex is OK. The discrimination that HCV carriers get can be a fierce social problem and is completely based on ignorance. The chance of a heterosexual couple having regular sexual relations transmitting the virus is zero point one percent per year,so a 1 in 100 chance with 10 years of regular sex. This does not reach a level of statistical significance.

I'm not sure of the context of your video here but it is a fact that hepatitis c can be exposed to air and still be infectious;i.e., using a razor blade. Why do you think people with hepatitis c are excluded from contact sports such as boxing and MMA? Hepatitis C can also be contracted through sex, particularly rough, abrasive sex, sex during the menstrual cycle and anal sex. It is important that these minor details be understood so as not to give people the wrong idea.
