The Wikipedia profile of Tarneit used to state that construction of the center would begin in late 2013 and take around 18 months to complete. The website now says that construction is due to begin in 2015. I assume that there have been some planning or finance issues with the development, because the big sign saying coming soon appeared around 18 months ago and some site work appeared to begin around the same time. This is very frustrating because i live very near by and it will be a good selling point for my house.
It should already be actively open.
