@birdsfromspace,
shop around the internet, i think mas mababa ang premium sa coles insurance, they have car and other types of insurance, try browsing sa webpage nila.
even if u have an australian license, i think may excess payment na babayaran, depende ung amount sa insurer, starts from 500 up..un lng ang pagkaka alam ko...and if u have an AU license, y still use PHP license..may I ask what type of visa do u hold, kung PR ka na, u need to have that license after 3 months of stay...hope this help
and are u planning of buying a 2nd hand car? i'm selling one of our vehicle, seldom being used at this time, 2008 toyota aurion ATX, +107K odometer reading...V6 3.5L bluish silver colour, good running condition, properly maintained,
