Hornet, the species of termites discussed in that forum are American termites. Yes, you can do what they do, however you will have to travel to the top end to collect the Mastotermes species that will reproduce as the American termites do. Our termites local to Brisbane however, do require a Queen and the base colony to sustain itself.
I would recommend reading Geckodans post again, as he has the method you will need to use here nicely sorted out for you and pretested.
I would also recommend the 'tree nest' species (Nasuititermes walkeri ) over the ground species (Nasuititermes excitiouses) as the tree species does not have a nasty mandible and are not likely to deliver a nasty 'bite'
