Unfortunately, the main source of flooding in this Deagon area is Cabbage Tree Creek. Did some research on Deagon previously in response to a Somersofter wanting to buy a unit nearby and wondering why so cheap.
Agree, beautiful area. I once got it into my head to buy a milkbar in Sandgate on Brighton Terrace nearby Deagon. Drove up and down the whole area to Brighton, then crossed the Houghton Highway to Clontarf, Margate, then Redcliffe and back to Sandgate, then to the The Palms Hotel in Virginia where I was staying. Noticed a lot of boutique apartment buildings were empty and selling near the Redcliffe foreshore, I wonder whether the apartments finally did sell or not.
