No one says it's impossible, just too expensive compared to other options. Being so far north, Finns don't have the cheap and easy access to solar we have.
But I'm not sure why you think it's easy just because the Finns did it.
Finland has very advanced tech and manufacturing capabilities compared to Australia. They are the home of Nokia for example. Oura. Many other very high tech hardware companies.
Australia currently does not even have the technical infrastructure to manufacture an ancient brick 5110 style Nokia phone from the 90s. Not from scratch.
I don't think the nuclear proponents realise just how much technical infrastructure we simply don't have.
Most of our economy is digging up dirt and farming. We do hardly any value add anymore.
Nuclear would absolutely be harder for us than the Finns.
