Try looking up physios in the yellow pages, thats how I found mine. Sally obrien in if anyones in brissy. You don't need a referral but Im not sure, you might get more back if you have one.
They have the exercisers, or they are available online, or you can just use fingers. Is this tmi? I think you can get a rebate if you buy it from them.
I can track down exercise routine if anyones interested.
