Have renewed my car licence twice now (1yr to 5yr and then 5yr to 5yr due to renew again next year) and both times the experience was pain free and efficient, infact when I first got my licence it was the same, I had no IDP to support my Aus licence so had to do the full theory and practical test but it was easy.
Am going to get my bike licence in December when our forced holidays happen, hopefully that goes smoothly as well.
