I told a friend recently that we never had a trip gone as planned , There are so many unknowns that you need to be flexible enough to go with the changes. But this time it's new , the change happened before we left. I found out yesterday that our bikes will be a week late. This is why Air freighting is a good idea unless you are flexible to move your plans a week which we are and hence we will start a week later than expected .
That said we plan to start our journey from the west (Perth) and go east (Brisbane) we are also looking at renting bikes in New Zealand for about a week to ten days since shipping them from Australia will be time consuming and we rather be traveling than going through the process of shipping the bikes and clearance.
