Yes cat you can run LOR controllers in 240v. Most of us have actually stopped using the 240v controllers and are using DC controller with low voltage lighting but thats another thing
But all it is is a little bridge connector on the controller that will enable either 110v or 240v
There is a large backlog with LOR controllers at the moment and supply to Australia may be cutting it thin before christmas. But here is the link to the LOR shop http://store.lightorama.com/diyproducts.html
There are no Australian distributors for LOR gear that i know of
There are other options available to you other than LOR we use a range of options that are LOR but require a bit more DIY but are considerably cheaper and more flexible
It's exceptionally unlikely that you'll get any LOR controller that isn't ordered already by the usual 1st of December switch on. If you want to go with LOR gear then you are probably going to be better off having a post in here and see if 1 of the locals has the gear. There's been a fair few change hands around here over the last few months.
