A few things that come to mind:

Fuel reduction burns (reduced season vs cost savings or lack of urgency)
Fire trail creation and maintenance
Environmental laws regarding land owners can do on their own land and where allowed, green tape complicating permitting.
Locking up of parks to removal of firewood and periodic grazing of cattle
Use of rangers to identify and monitor emerging issues in parks
Allowing people to build in fire prone areas
Lack of fire proof underground bunkers (community or on individuals property)in fire prone areas.
Land clearing around critical infrastructure (eg Telstra towers)
National coordination of aerial firefighting assets
Adequacy of aerial firefighting fleet
Use of Military forces
Training of Military forces to undertake firefighting
Sustainability of volunteer firefighting membership when faced with a long battle.
