Fellow Aussie here. Not sure where you are, but here in Melbourne I've found a few specialty cafes that serve a deconstructed long black... basically an espresso with a small cup of hot water on the side, so you can experiment with how much you want to dilute it.

Nanopresso (another Wacaco travel brewer). I'm only in the office two days a week so I couldn't justify a full office coffee setup. I grind enough for two shots in the morning (I have the 'barista kit' with two larger baskets) and I can pack everything neatly into the Nanopresso.
