jadunlop, the CBT in England is not an official endorsement on your licence, it is a certificate that allows you to ride up to 125cc on L plates (you are not tested by an official examiner). this means you cant transfer it to OZ.
If you were to get your full motorbike licence a 3 day course (inc test on a 500cc) for about £500 you can ride any size bike and can transfer it to an OZ licence.
Looking at the restrictions etc once you pass your test here, I would do the motorbike licence in England
Hi there, I'm thinking of just getting a learners for commuting. I don't ride motorbikes over here in Scotland and I don't intend to get caught up in bigger motorbikes etc... If we settle down within 10 miles of where my work is I'll be using my bicycle for commuting. The learner motorbike just gave us more range to find a suburb to live.
