* The traditional one-finger salute, where the middle finger is extended while the other fingers are curled inward.
* The "two-finger salute", where the middle and index fingers are extended while the other fingers are curled inward.
* The "backhander", where the hand is turned palm-down and the middle finger is extended.
* The "shocker", where the thumb and index finger are held together in a circle while the other fingers are extended.
The meaning of these gestures can vary depending on the context in which they are used. For example, the one-finger salute can be used as a gesture of defiance or anger, while the two-finger salute can be used as a gesture of victory or triumph. The backhander and shocker are both considered to be obscene gestures.
It is important to note that these gestures are not always considered to be offensive in Australia. In some cases, they may be used in a light-hearted or humorous way. However, it is always best to avoid using these gestures unless you are confident that the person you are gesturing to will not be offended.
