In the Residence and Tax section - "List all of your travel documents or passports covering your 5-year eligibility period. "
Should this include PR card, VISA, Work Permit, apart from Passport?
Some people like to list absolutely everything here, but it's not needed (although it doesn't harm!)
Listing the passports only is enough.
FYI, the "travel documents" referred to here are an equivalent to a passport for refugees.
