Hi all, It has begun, all toll roads and bridges in sunny Qld are becoming cash-less So I have begun the quest to find out the options, I emailed Queensland Motorways Ltd and got a nice responce, very polite, see below for details. I Quote "Etoll can be used on a Motorbike. We need to advise you that Etoll is not waterproof. So if it gets damaged by water you will be required to pay a $40 replacement fee for a new Etoll. Most riders have a lot of success by inserting it in a plastic bag, putting it inside an old mobile phone case, then with elastic on both sides of the phone case and placing over their left arm." As if "They have also being known to bounce off the bike if not secured properly. If device is damaged will be required to pay a $40 replacement fee for a new Etoll. Please feel free to call into one our Service Centres and we will be more than happy to show you the different attachments we have." I will investigate futher, Cheers Chris.
