Medina and surrounds I beleive is a place to invest in, but it is a long term investment. There is the new development Windsor Hills from Satterleys and as stated the train line.
The Industrial area that is situated to the west along the coast will go due to pressure from Locals, investors, developers and Council.
Also if the Mariner gets the Environmental go ahead in Rockingham all systems go.

Also previously in this forum Exmouth was mentioned. The reason the Indigenous People do not go out to the Peninsula is because in the Dream Time a large Tsunami washed all living creatures from it. And yes development has stated on the Mariners and if I had the cash I would buy and run it as short stay accomodation. It is beautiful there.
