Thanks @Marisawright for the help! Currently I'm not planning on putting on a show - I'm looking more at TV and Film roles so that last little section of your message is incredibly helpful in regards to that. I am definitely aware that the competition will be fierce, I don't doubt that for a second but then I guess the competition within this industry is fierce no matter where you go. I'm currently in London where a huge proportion of the opportunities are and it is still insanely competitive here and the city is saturated with aspiring actors, LA is the same.
As much as London is great and filled with the creative industry, the lifestyle here is nothing compared to Australia's lifestyle. And this is why I'm interested is moving over because if there are acting opportunities in Australia then I'd much rather be living where I used to live in Sydney and making the most of the lifestyle out there rather than being stuck in a smoggy city where nobody smiles at eachother and there are absolutely no beaches, unless you count a bit of mud on the side of the Thames haha!
Thanks so much for your reply, appreciate you taking the time to reply and if you have any other info then that would be amazing!
