I'm in Melbourne. This lockdown's going pretty much the same as the last one for me, though I'm doing essential services work so I'm in a really solid position. Most people seem pretty relaxed, but its real bad if you aren't in a good spot like everyone who's lost work. The lack of income support is real bad, Jobkeeper and Jobseeker made a huge difference, but unfortunately the liberal party's committed to not doing that again for ideological reasons. I honestly wouldn't say I'm doing great, but I'm trucking along as well as you can. The main problems are lack of going out for dinner after work, a bad habit I thoroughly enjoyed, and how it impacts dating.
I'm mostly concerned about Sydney since that's got a bigger outbreak with more relaxed rules. Plus there's a lot more ignoring restrictions apparently.
