Adelaide is said to be the only capital city in the world with resident pods of Dolphins living in its tidal river. I have seen them on numerous occasions swimming in the Port River. The most in one time was around 20, they seem healthy enough and have several young with them. These pictures I took on my way home from work one morning. If anyone is interested I have some short mpegs of the Dolphins at play, email me and I then can forward them on to you. tlubcke@hotmail.com
