A suicidal mission

Accepted a "suicidal mission" coming to Sydney, not really that I am dying to come here, I was sent to Sydney to conduct a training which is quite difficult to be done by one person and also, the main thing is I am not the Expert in this! The IT guy was need more time to apply for his visa, and the success rate is unknown, could be 33% only! That is why I call it a suicidal mission coming to Sydney, nevertheless it is a great account that everybody is fighting for. But I am a bit stress out with this assignment, the country manager of the Sydney office is well-known with her bad temper. If I didn't do it right, I think I will be in big trouble...
