I can't help with the situation to-day, but when I first arrived in Adelaide in 1960, I wasn't aware of any state government advice sessions for new arrivals. However, in those days Adelaide had a population of only about 500,000, and with so migrants coming especially by ship, the task would have been enormous.
I came by myself, but fortunately could stay with a sister for a while before renting a room in a shared house in Prospect, and then renting a flat on the Anzac Highway. Many families were put in hostels which was a practical help, though these days I can't imagine anyone accepting accommodation in Nissan huts. We felt like true pioneers in such a far distant country, just two big metal sheds at Outer Harbour to greet and process us, the whole area could well have been at the end of the earth!
