I've never had to go to Adelaide's southern suburbs. So I've never been.
A sore mistake on my behalf. If you have been in my position, head to Sellicks Beach/Hill. Adelaide turns into another country along these roads in the winter, the only reminder of this country being the copious amounts of trash just strewn along the roadside (how disgusting that is is another conversation).
Another landmark to at least scope out is the Buddha. Still surrounded by construction and a little underwhelming while blocked off to the public, but still a sight to see.
