you don't need an agent to be a shitty extra.
Like I said before - head down to Fox Studios central casting and sign up for a casual extra job.
But, if you wanna be an actor/talent whatever steer clear of those SMH adverts. (especially the one that says "established 37 years - yes, established in the stealing and swindling of ppl's money for 37 years!!!)
They are the fake thing! (speaking from experience) The minute you call up or turn up, you are expected to give them a joining fee and a fee on top of that for your headshots - I went down to Sydney one time and I had to join for $100 then I had to pay a further $120 for my "headshots" .....My headshots were done with a cheap ass digital camera and my proof sheet was a crappy black and white print out (with those blank lines and all) of my crap pictures I could have done myself while complety high on crank!!!
- if they ever ask you for a joining fee kick them in the neck and run away...but make sure they havent already stolen your wallet!
REAL agencies don't need to advertise - they are successfully run by their reputations.
