In that case, focus on the results (culture of place, economic character, sustainability etc.) of the urban dynamics (probably urban decay/renewal amongst others). I'd probably give a bit of background to the urban dynamics (ie: how they occurred, what happened) but i'd spend a lot of time talking about the change, comparing statistics, photos, etc.
as for resources try:
http://www.asknow.gov.au/ (as a librarian for help)
OR
http://www.nla.gov.au/infoserv/rf_form.html (send the question in to the national library of Australia and they'll send u back some useful links. this helped me to get through quite a few assignments...u need to allow a few days though)
