Many countries charge money to issue visas to people wishing to enter, and many charge different fees for citizens of different countries.
On my current trip the most I've had to pay was $20. One other country I thought about visiting would've cost $100. And I've heard other travellers talking about some visas costing around $300.
I've been wondering which country charges the most for a normal tourist visa to citizens of which other country.
As a bonus question I'm also wondering which country charges the most for a citizen of Australia to visit.
To be clear, I am only interested in tourist visas for whatever duration - not other kinds of visas. I am specifically not asking about any other costs that a person applying for the visa might also have to pay.
