My thoughts are no...but I thought it might be interesting to discuss.
Looks like not only did Brisbane pick the same bikes as a lot of European cities they also cloned the web site, see http://www.en.veloh.lu :-) It's a pity they didn't also use the same rates. In Luxembourg the first 1/2 hour is free, additional hours are an additional euro to a maximum of 5 euros a day (AUD6.20). That would get you 90 minutes in Brisbane.
As a contrast the city bike I hired in Brugge was 8 euros for the day (AUD10).
I wonder if tourists suffer from sticker shock? :-)
