Hi Cloudyseas,

JMO, you cannot ever have too much detail. See something… I reckon feel free to add it. There is a LOT more to mapping than adding a few streets.

5m average accuracy? If only… Seriously though, a run of the mill hand-held is fine, if that is what you have. The accuracy of your** work will have a larger bearing on the final outcome.

As a starting point, I would recommend a thorough read of the wiki. As to updates, this http://www.osmaustralia.org/ might be helpful.

Cheers
