We move a bit with defence but our moves are paid for.
The removalists come and pack everything but clothes. I actually don't like it that way!!! I think it is much better to pack your own stuff so it is organised! The packed stuff from like 4 different cupboards in one box when each cupboard would have filled up a box easily! grr...

Go to woolies/coles and ask what day they do their night fill because you can go get a heap of boxes for free!!! and is there a possibility of hiring a moving truck and driving it yourselves?

PS we have family in Canberra, it is a LOVELY place to live!!!
Good luck!!
