Total Eclipse of the Moon: 2022 May 16

which given your location tells you what to expect. For me the news is bleak: full eclipse begins at 05:23 local time, and sunrise is just 4 minutes later, so the darkening of the moon's face probably won't register against the rapidly brightening sky. But the site overall is a go-to for easily digested information on all things daylight.
In short, maybe the countdown is 3 hours off? And it's trying to communicate the time left until the maximum?
- "6:32 pm: Penumbral Eclipse begins / Below horizon"
- "8:29 pm: Total Eclipse begins / Below horizon"
- "8:34 pm: Moonrise / Rising, but the combination of a very low moon and the total eclipse phase will make the moon so dim that it will be extremely difficult to view until moon gets higher in the sky or the total phase ends."
I think you mean PDT. Which may or may not account for some of the miscalculation.
I usually say "PT/MT/CT/ET" for those not in the list of stateside exceptions since it just removes ambiguity.

Though it might soon be moot given USA is moving to permanent DST, so rather than people using PST wrong some of the time, it will be all of the time.

For sunrise/set and moonrise/set calculations you also need to allow for refraction in the Earth's atmosphere (around half a degree or so). Also for moonrise/set you need to allow for the parallax of the Moon's position because you are standing on the surface of the Earth not the centre (up to 1 degree difference in position). This all assumes a spherical Earth and an Ocean horizon. And the rise/set time can changes a little bit with your altitude above the horizon.
For latitudes near the Arctic/Antarctic circles any method based on iteration (as in Duffett-Smith's lovely book) is going to have convergence issues because there might not actually be a rise/set event near that day so if you really want an algorithm that will work anywhere on Earth you'll need to use a method based on fitting a quadratic curve to (say) 24 positions calculated for the day. Have a look at [1] in a library. The code is in Pascal, but it is the search method using a quadratic fit to sets of 3 consecutive positions you want.
Just for low-precision lunar positions, an interesting alternative that also summarises the various methods was produced by NASA [2] for space craft use.

Full moons are always directly opposite the sun. You'd be more concerned about it disappearing beyond the horizon.
The moon turned red at some point. It was a pretty eerie experience.
If you can do so at least once in your life, I recommend it.
Total eclipses aren't all that common. Eclipses occur every six months, usually in pairs (one solar, one lunar, two weeks apart), but most are partial eclipses.

Knowing Sydney, they'll probably blow up a ton of fireworks or something...

I've done a bit of searching and can find nothing that corroborates your statement. If you could link me to a study or other data source showing a correlation between lunar eclipses and specific weather events, I would be interested.
Edit: As noted in a different comment, solar eclipses do impact weather: https://weather.com/science/space/news/2019-06-28-solar-ecli...

Of course even down south here at 56.5°N it still gets light really early this time of year, so it was already light enough to see that I was not going to see the moon.
