OK simmer down people.
O'Sullies beach is an area that, generally, has so far failed to revamp itself into something more posh than it is. Yes, the dog beach is there but that's great if you have or want a dog. Yes, the refinery is there but it is going to be dismantled in the next year or so and once that land is cleared it will probably become a new housing development which will change things for the area as a whole. Yes, there is industry but only on the Lonsdale Road side.
There are only a couple of local shops and no pub. There is one bus route that runs through it and there are only two roads into and out of it - one towards Christies Beach and the other towards Lonsdale. The desal plant is on the other side of the refinery complex so it's far enough away not to matter.
When looking at areas on Google maps I always take not of how many swimming pools I see. Generally where an area has more pools you can bet the household income is higher and the houses are worth more.
Would I live there? Probably not, however I'd sooner live there than back in the UK.
