What travel documemts do I need to enter Canada from the United States by land? And then Canada back into the United States by land?
Im an Australian Citizen, 21yo. I will be in canada for about 7 days before I come back into the United States.
For entering Canada by land you just need your passport, see: http://www.cic.gc.ca/english/visit/visas.asp (search Australia).
For the States it seems you just need to fill out a form (when entering by land with a passport from a Visa Waiver Program country like Aus): https://help.cbp.gov/app/answers/detail/a_id/1132/~/citizen-of-visa-waiver-country,-wants-to-drive-into-u.s.-from-canada-or-mexico
