Iain and others interested in landscape studies and cultural geography:
 
You might find the introduction to and essays in Rebecca Yamin and Karen
Bescherer Metheny, eds., Landscape Archaeology:  Studies in Reading and
Interpreting the Historic Landscape (Univ. of Tennessee Press, Knoxville:
1996) of interest as well as useful in revising your current impression!
 
I don't know if any copies have made it to Australia yet; I've promised to
send one of my (2) copies over (to Latrobe, which won't do you much good in
Sydney!), but as usual have not managed to get the thing in the mail.
 
Cheers,
M. Beaudry
