I want to know the answer to the following question:
What types of surburban development did Melbourne policies promote?
All the background I'm provided with is that "However, after 10 years[when?] of planning policies to encourage medium-density and high-density development in existing areas with greater access to public transport and other services, Melbourne's middle and outer-ring suburbs have seen significant brownfields redevelopment.". Is that enough to answer the question?
Answer: yes
