These two photo's from Google Earth show the transition of Bay Park to a housing estate.
First photo taken in 2003 - sorry it's a bit fuzzy. Note the Rorison house is just foundations now but the red shed still stands behind it.
I visited the site at this time and walked around what was left of the house etc... it was very sad but predictable that BayPark would go eventually ( noise was already a problem )
As a point of reference in the photo's the house at the bottom right on the boundary of Rorisons with the 3 rooflines is still there and the driveway in to Bay Park appears to be in the same position as the one now into the housing complex.
This photo is from 2013 showing complete coverage of the site
