I decided not to renew my passport before starting this trip because passports are very expensive in comparison to my income and my low travel budget.
But when asking people I find their passports in other countries are much more affordable than in my country. Typically Australian passports are in the range of roughly double the price friends have to pay in other developed countries or other western countries.

Is this a rip-off? Are most passports in "rich" countries so expensive or are they roughly half the price as the impression I have so far?
It's true I overlooked passport validity. That's the most important thing I've learned with this question. Assuming all passports have the same number of "visa pages" I should instead ask what the "price per year or decade of validity" is.
