I noticed a lot of duplexes being built around the established parts of Toowoomba when I was back in April. H&L development through Toowoomba still seems to be fairly limited to the Cotswold Hills, Glenvale and Kearneys Spring areas.
Further to Coota's comments, the sub 300k market for houses in Toowoomba is very much limited to older houses in the western and northern suburbs, the sub-300k market for houses in the south and east is next to non-existent any more.
