Not really hard for me, it has always been that way down here so we all learned to drive that way but if say someone from U.S.A came down under it might be a challenge to start with.I went to hawaii a few years back and rented a mustang convertible took me about 15min to get used to shifting with my right hand, It was different but fun.the gear pattern does not change 1st is still top left.
