A source in Aus for 24 volt LED rope lights is http://www.santasledlights.com.au
If you mention this forum you will get a 10% discount too.
Looks like its time to get rid of all the mains powered gear here.
I'll chime in too that these guys are excellent to deal with. Emailed Friday to ask about discount - got a response Saturday to say discount had been automatically added to my account. Ordered Saturday afternoon and my stuff arrived today, Tuesday. I got white ropelight, connections for it and 2 power supplies. Granted I live 2 hours from the Gold Coast, but I thought that was extremely good service. I'll order from them again for sure.
