Two Whales in Derwent

Just thought I would let interested people know that there are two large whales currently making their way up (towards town) the Derwent in Hobart.
A Parks ranger was just down at my place near Cartwright Point reserve on the Taroona/Sandy Bay border trying to spot them as they made their way up the river (he had chased them from the south). I had seen them before he arrived, but we couldn't spot them again. They will likely be visible around Sandy Bay/town most likely, and will eventually turn around.
The ranger said they are likely southern right whales, as he had two of those yesterday further east.
