From the datasheet Section 28.2, for an UNO running at 5V a digital input will read high at a voltage of just 0.6V. Is this correct?.

VCC = 2.4V - 5.5V
- “Min.” means the lowest value where the pin is guaranteed to be read as high
Is this correct?
Given the conditions, that's my interpretation.

No, the spec is saying that the minimum input pin voltage needed to be detected as a HIGH is .6 X Vcc (60% of the actual Vcc voltage being used). So for a 5 volt arduino board the minimum input pin voltage guaranteed to be detected as a HIGH is +3.0 vdc.
For a 3.3vdc powered board the value would be 1.98vdc.

Ah, TC beat me to it.
Yikes! Sorry about that.
Well at least you cast your answer as an interpretation, not a fact.
