Other documents as in you need your, PR Card/ COPR, passport... you will have to give the G1 written exam (no escape there). you will get an experience added depending upon the years you have the Indian permanent licence, so you can go for G directly and skip G2.... however you only have one attempt (not completely sure though) for the G using this route.... else you can get G2 (the only difference with G is alcohol limit... and insurance
) with every attempt you give for G it is $90 so it helps to practice properly before u give the G test.
