Any imagery can have a 'offset' from where it should be. And that offset will vary as you go up and down hills.
The LPI Imagery has much better resolution and less parallax error than the other sources .. I prefer it to any other images for its accuracy.
That said it is usefull to check with other images for more up to date things. I found in Coffs Harbour that the DigitalGlobe stuff is more current.
I'll leave others to comment on that address stuff.. no expert on that (yet). :)
