Do French people need a visa to go to Australia?

Except those who hold Australian and New Zealand passports, all people who travel to Australia need to apply for a visa or an electronic tourist visa (ETA).

E-visa processing is relatively simple. If you join a tour group, just let the travel agency handle it for you. If you do it yourself, please go to the official website of http://www.eta.immi.gov.au/, and click Apply for ETA. Please prepare a passport and a credit card. It costs 20 Australian dollars.

Passengers with electronic tourist visas are not allowed to work in Australia and stay in Australia for no more than three months.

I hope it helps you.
