OpenStreetMap
At short notice I had a trip to Tara, first opportunity in a year to survey the area..
Managed 99% of the towns streets was able to correct the Surat Development road from the Moonie Hwy to Tara,(Previous was from Yahoo - as was most in that area) as well surveyed tara-Kogan road and Kogan-Warra Road.. just have to tidy the map now.. Now to add a few of the local services..
The Yahoo imagery is not that good for this part of the world, I was surprised with the low errors with the main roads (luck and a little local knowledge)
My next out of town survey will be a quick trip to chinchilla.. I don't expect much time to drive or walk around.. but hope to add a few more streets - I think I am only 20% mapped there atm. and really need to add a few of the local services..
BTW: It is annoying that an error can display on the tile servers in less than an hour, but the correction will take more than a week?

nope, the tiles get rendered almost right away. You should save the location as a permalink and refresh (or delete your Browser cache). You don't see the changes, since the old tiles are still cached.

yahoo sat imagery might be low res, but since Tuesday we have Qld property boundaries to play with, which includes gaps for roads, rail and water ways etc... Not 100% perfect, but neither is sat imagery, but it comes in very handy as a secondary source to help with GPS inaccuracies etc.

I took a screen shot of Tara with the property boundary layer loaded in the background:
