How do you apply for auditions through the TV industies as an actor

You don't say where you are? I would suggest you look on this site in the auditions section join your local theatre as local companies are always looking for new members. You can also try an internet site called Auditions Australia if you are in Vic. Qld or NSW. If you are in Perth try Perth Auditions on the internet. Amateur theatre is not paid but your reward is the experience and on the job training and the nice people you meet. Once you have some experience and training then you can go to an agent and audition. If you are in Perth I know that Actors Now, Frog and Actors Management all have classes. Also your local independent theatres also often hold classes. There are also some high schools which have special programs for the arts for example John Curtin College of the Arts and Perth Modern in Perth. You need to audition to get into their programs, but if you get a good monologue and audition with it you have a good chance of getting in if you are good. There is a lot of competition for the places in these programs though. Training is important and you will need a good head shot and CV with experience and training on it. Try to get an agent, but you will need to audition for them to represent you. Reputable agents do not charge for you to audition with them. Once involved in all of the above you usually hear about auditions. There really is not much paying work about and so there is a lot of competition at the auditions. Independent theatres are one of the best training grounds other than NIDA, WAAPA etc, but you are a little young for them at the moment. Good luck.
