And not that remote.

Internet provision not all that far out of major Australian cities can be abysmal. I'm only 30 minutes drive from the centre of Perth and my options are currently 5G (operating at about 4Mbit), Wireless Broadband (performance promise - the download speed will reach 25Mbit at least once in any given 24 hour period!) or Starlink, at a pretty stable 120/20.

I'd love to not have to pay for it, to use what local/national companies can provide, but so far nothing comes close.

I am informed that the wireless system is due to be upgraded to support much higher speeds, but that was supposed to happen this year and there's not a lot of this year left.

I would think 5G could really improve that situation. In the states we have the 600 MHz spectrum on T-Mobile and can pull down decent speeds 30-150mb through trees 15 miles from the tower. Upload is not great.

Absolutely, I've had 5G modems within the metro area of an Aussie city and it was horrible.

It may or may not be relevant to your case, but every time a story like this comes up I will remind people in general that fiber-optic cable is 50 cents per meter (probably $1 per meter Australian), wireless links cost equipment and a regulatory approval fee and are easier in less densely populated areas, and there are tons and tons of stories of people dissatisfied with their ISP creating a better competitor, your neighbours are likely as frustrated as you if they use the Internet, and there is no minimum size to an ISP.
