The Third Doctor is perhaps my favourite Doctor thus far and whilst he and companion Jo Grant are characterised fairly well here this doesn't feel much like a Third Doctor story, with no UNIT, no Master yet still set on (virtually)contemporary Earth. The TARDIS lands on a salt lake in Australia in 2028 where they discover strange statues made of salt which look worryingly like people.
I really liked the setting and the idea of the Third Doctor 'blokarting'- being a man of action I could picture Jon Pertwee doing that- but this lacks in some of the key elements a really good Doctor Who story needs. The first of these is a villain, or at least a strong sci-fi element, which this story doesn't really have. Another is a strong guest cast- here we only really have one woman and a dog and oddly quite a high proportion of the story is told from the dog's point of view.
I could see that Trudi Canavan had chosen a place that she knows and loves because the setting is really strong here but it feels a bit like he had a setting and then tried to build a Doctor Whos story around it, and didn't do a terribly good job. In fact the solution is almost identical to one of the Ninth Doctor stories.
Not a complete failure but my least favorite of the Time Trips stories so far
