Drawing Maps of detailed Australian regions

Hi all,
 
I'm trying to draw a bubble plot over a map -- where the map shows local
government areas (LGA) in Australia (or other structures under the
Australian Standard Geographical Classification), but am not sure where I
can find the data to plot such maps (e.g. draw the state of Northern
Territory but also showing LGA divisions).
 
Any help will be greatly appreciated, apologies if this is a simple
question -- this is the first time I'm trying to draw a map in R :).
 
Cheers
Kev
