Looks like I'll be visiting Adelaide for a couple of weeks, with a possible follow-on trip in the future. Three questions, quasi-electronics related...
(1a) Are there any electronics or computer hacker groups that have meetups?
(1b) Any forum members in Adelaide?
(2) Any brick-and-mortar electronics store(s) in Adelaide? If not, what is the local go-to app for quick, next-day delivery? No matter how hard you try to plan ahead, experience taught me to have a plan B in case you inevitably forgot something.
(3) I really like learning about the history of technology, electronics, computers, etc. Are there any such museums nearby? Hardly nearby, but of course there is the Canberra deep space tracking station. If I got myself in the vicinity, do they have a museum (one might argue the whole place is itself a living museum)?
