One possible version：
Boys and girls,
May I have your attention, please? As we know, some sixty students from Australia are going to pay a visit to our school on July 2nd. We’ll meet them at the school gate at 8:30 and then take them to the hall, where a get-together is to be held. At around 10:20, we are expected to show them around our botanical garden and the school-run factory. It must be exciting to watch a friendly basketball match in the gym at 11:00. After that, the guests will leave our school at 12:00.
Besides, please remember to have good manners all the time and talk with them in English as much as you can.
That’s all. Thank you.
