Ive spent a few days trying to find a free license (free to distribute) digital map of Australia that is 1:250000 ideally 1:100k or 50k but that's not going to happen I think.

Does anyone know where I can get this?

Needs to be a georeferenced topographic map of Australia in 1:250000 at worse and free license to redistribute.

Land information New Zealand as a great free source with 1:50k http://www.linz.govt.nz/topography/topo-maps

Geoscience has this for $99 but not sure if this is a free license or not....

Any map gurus know of any resources where I can find this???
