Not all countries have hilariously huge beaurcracies of elected officials. In this case the article is about Australia.
Here we vote for senate and the house. The prime minister is chosen by the party which controlls the house. Cabinet positions such as treasurer and AG are chosen by the prime minister and confirmed by the governer general.
Local officials, controllers, and judges are apolitical positions and not voted on.
Propositions and measure are "yes/no", not a ranking of positions.
You can make your own (or print one from a party's website) "how to vote" card before you go to the poll, and then fill in your ballot to match. Or you can decide when you get there.
It takes under 5 minutes to vote for everything in total, not 5 minutes per vote.
