Trip in Australia

Hi guys, it's been a long time, hasn't it? We are now here in Sydney. From Ho Chi Minh Airport (Saigon), we flew here in Sydney. We're enjoying our travel here although it's cold because it's now winter here. And it's already dark at around 4o'clock so we have to go out in the morning and come back until dark.

As of now, we already visited the Sydney Opera House, Royal Botanic Gardens, Harbour Bridge, Hyde Park, Martin Place, St. Mary's Cathedral, Queen Victoria Building, Belmore Park, Sydney Tower, Pyrmont Bridge, World Tower, Sydney Aquarium and Blue Mountain. We went to the Echo Point and walked for about an hour to the Scenic World then took the railway and cable car. It was our second time there. We went there last time but it was raining and we couldn't see anything so yesterday we went back there again. It takes two hours going to the Blue Mountain by train.
