Replacement Drive Belt for a Janome Memory Craft 7500?

Where can I obtain a drive belt for my Janome Memory Craft 7500.
The details on the belt itself are:
Bando synchronous belt 163XXL

Janome repairers say they have to order and it will take weeks. I need to pickup one ASAP from some where in Melbourne Australia or fast from internet purchase.

Note that the local Bando agents typically only stock belts for cars and mining conveyors!
