Further research on heat-pump HWSes - I have some anecdata from other Canberrans now saying they are fine in this climate.
The unit I've researched most also includes a traditional 2.4kw electric heater which it switches to if the temp drops below a certain temp (-7C, about as cold as it gets here), so it doesn't just stop working entirely if it's cold. (A basic electric one says 3.6kw so I'd need a new circuit run to replace my dumb gas unit either way).

Fun fact: Hot water systems in Australia are required to keep stored water at 60-70C to prevent bacterial growth, but must not deliver it to any tap above 50C - AS/NZS 3500 requires a tempering valve to drop the temperature to 50 (or 45 in schools, old folks' homes etc): https://bestplumbers.com.au/plumbing-guides/hot-water-tempering-valve/ Less fun fact: My HWS, original from and installed in the mid 90s, when turned up to maximum in mid autumn, delivers hot water to my kitchen sink tap at 53.6C. Oops.
