Rio, always look after yourself first on mental health sites! As you see, you can't do a whole lot for your friend in Australia since you're in Scotland. But what your friend decides to do is his decision and not something you can "help" with. He does live there and can find out local resources! About the best you can do is to let him know you are there if he wants to talk about it and suggest he look up resources and let him know you'd really be sorry, unhappy, miss him, etc. if he were to suicide. You can only give him as sincere, consistent a part of yourself from online as you can and hope that makes a difference to him. We can't force other people to care, be happy, get help, etc. But we should always make sure we ourselves don't get overwhelmed by other people's problems because then we can't be at all helpful to them or ourselves!
