No comment on the import, but I wouldn't use the Electoral boundaries to
derive any kind of state boundary.

Also since data.gov.au just pulls the data from the various different
government agencies, I would suggest getting it straight from the source.

You would want the last one listed: State (S/T) ASGS Ed 2011 Digital
Boundaries in ESRI Shapefile Format. Note the copyright for this

Various other different admin levels are also at

2011?OpenDocument

Beware though, that these are not the official state boundaries, or
other admin boundaries. They only represent an ABS approximation of the
official boundary with the aim of generating statistics on these areas.

For most purposes they are good enough representation of the actual
boundary for us, especially in lure of a better source, and without any
on the ground mapping.

I hope this has provided some insight.
