Hello, Platypus, this thread is a good idea, thank you.
I have DS2 and family living in Sydney and have visited twice. Unfortunately , last November/December's trip to there and New Zealand got postponed due to Covid, and now that postponed trip has been cancelled by me for the indefinite future.
My late DH and I were great travellers but never went to Australia because we imagined it would be full of boring white people like us! So it was South America, China etc etc. When he died, I went out there and loved it. I've always preferred the big open spaces to rather confined little England but even more than the country, I found Australians themselves greatly to my liking,
Trains having been mentioned, I will add that the last time I visited, I flew into Perth and travelled across to Sydney on the Indian Pacific. It was 3 whole days to cross a country! When a child, I loved studying the atlas and the name Nullarbor Plain fascinated me so I had a long held ambition to see it. It did not disappoint. It's huge and seemingly endless and beautiful in its way. I was definitely not bored! The food was great and we stopped for various outings, one to the Kalgoorlie gold mine at night...an absolutely vast hole in the ground. Just one of the great trips I've had out in Australia. I'd be very happy to live there permanently but for various reasons, it's not on now.
I'm going to be very interested in hearing news from the country.
