Taichi- My first week in Sydney

I'm from Japan.My plane was supposed to arrive at the airport on a Sunday morning.But I arrived at the airport on a Sunday night. Because my aerplane had trouble. So It was delayed by one day.I went to hotel that was near. I stayed for one night.I departed early in the morning. so I was still sleepy.I arrived at Sydney airport safely but I was very late. I didn't know how I could go to the hostfamily, and it was night. I wet to hostfamilies home by taxi. so There was no help for it.
