Yeah so that’s a coastal city south of Sydney, NSW, I don’t know much more about it beyond a few quick visits and their university. I had a look at their official website (https://www.wollongong.nsw.gov.au/) and I like that it’s got a separate homepage for tourists and residents, so that site will have some useful tips for him.

Australia has a reputation for the dangerous critters but it’s exaggerated a bit. It’s not like we have bears or wild dogs (apart from dingos), the venomous animals generally want to run away from us. The exception would be crocodiles, and crocs aren’t native to NSW.

I don’t think there’s anything too wild about our culture which would trick an internet-connected east coast fella, maybe that a fair bit of our (colonial) culture is closer to the UK than the US, so we might share things like understatement and a drier sense of humour.

I don’t know what the situation is in Wollongong, but in Sydney there’s plenty of opportunity to explore different cultures. Depending on where you are on your east coast, you might have had similar immigration waves (e.g. initial European colony states, Central/South European WWII immigration, Pacific conflicts and general Pacific regional interests (e.g. gold rushes), Middle Eastern conflicts immigration) so in cities there’s plenty of great cuisine from all around Asia, Lebanese/etc. food, Italian and Greek food, and plenty else around. Italians are sometimes credited with fueling a notable coffee culture in our cities. Wikipedia says Wollongong has Macedonians rank unexpectedly high up the demographics chart (~2%).
