Please let those of us here know when you do come and we'd be more than happy to show you around or help with your search! I'm originally Australian, was in NY for 8 years then South Bay 1 year, and sea coast NH is by far my favorite so far for many reasons. 1 hour from Boston is also a huge plus.
I’d love to help you find property in New Hampshire, it’s awesome here. When you say “good indoor spaces for work and hangouts”, for how many people, and can you be more specific about your desires for the space?
I second this, New Hampshire is awesome, and Portsmouth has a very South Bay feel to it. It’s a really vibrant community, and the nature is beautiful. Pawtuckaway park is one of my favorite hiking spots. Also super close to Boston. Highly recommend New Hampshire!
Australia doesn't have a strong intellectual culture (as an Australian that is why I moved to the USA).
Australia is beautiful and a wonderful place to relax though. However immigration there is very difficult.
