Yes, living in WA, I have -went on a small boat trip to show an overseas friend last week, and we saw dolphins several times right alongside our boat. They jumped in the air continuously, almost like they were giving us a show.
Yes, quite regularly here in Perth. There is a pod of them living in the Swan River and often when I'm walking or cycling there I'll see them swimming past. Further north in Western Australia, at Monkey Mia (near Denham on Shark Bay), there is a famous group of wild dolphins that come in to shore a few times daily to be fed. They're amazing and visitors get the chance to see them very closely. Thousands of tourists from all round the world travel there just to see them....so if you love dolphins and would like to see them up close this is the place to visit!
Yes, twice! Once I went on a wild dolphin retreat to Tangalooma Island in Queensland. The dolphins would come up once a day to take a fish from a tourist's hand. They are not fed all the time, so don't lose their natural ability to fish. It was a quick experience and I got a nice photo out of it. Years later, I visited a Zoo on Aruba where people can swim with dolphins. I was pregnant so didn't go in, but the dolphins there were lovely and came right up to the shore for a kiss!
I have chased dolphins around the world, so yes I have seen them many places - in Jervis Bay, on Dee Why Beach, in Coffs Harbour, New Zealand, Mexico, Hawaii. I've had the pleasure of swimming with them several times - breathtaking experience each time.
