Can't see anything about punishments for those that don't get vaccinated. Fines I'm guessing.
There will be fines, but there are no details yet as the exact law will have to be worked out in the next few weeks and the government has already said they want to include various interest groups (like unions, Chamber of Commerce, legal experts) in the process. That's why they've announced it for February which is too late to fight the current wave. There is precedent as we already had compulsory vaccinations for smallpox from 1948 to 1981. The fine for not getting vaccinated was somewhere around 1100 Euros.
As someone asked earlier about booster-shots and how they work with vaccine passports/lockdown for unvaccinated, the passports are valid for 9 months after you've gotten your 2nd dose of the vaccine. So, if you had your 2nd shot 9 months and 1 or more days ago the passport is no longer valid. So, I got fully vaccinated on 18th June and my certificate was valid until 18th March next year. Getting a booster extends that period again (don't know for how long, but I would imagine it's 6 or 9 months for now until we know more about what immunity is like after three vaccine doses). So, if you don't get your booster after 9 months your vaccine passport runs out and you are basically the same as someone who's unvaccinated in terms of being able to use the certificate to get into events or restaurants.
With getting vaccinated becoming mandatory in February they've also announced that they'll shorten that period from 9 to 7 months. The 9 months were chosen, because no one knew how long immunity lasts and 9 months was the time where they thought boosters would be needed. Now they recommend boosters after 6 months, for the AZ-vaccine they've shortened it to 4 months and you're getting a mRNA vaccine. If you've gotten Biontech/Pfizer or Moderna you can also get a booster after 4 months, but the official recommentadtion is still 6 months and if you get it earlier it's an off-label use you have to agree to. Will get my booster next week.
