Crimes Act 1961, ss 216G-216K
Taking intimate photos or videos (“intimate visual recordings”) includes where someone takes a photo or video of you in a private space where you are naked or partially naked, or only wearing underwear. It includes photos or videos of you involved in a sexual activity, showering, using the bathroom, or getting changed. This also includes photos taken from beneath or under your clothing (sometimes called “upskirting”).
If someone takes intimate visual recordings of you without your consent, they are breaking the law.
