yep - not all ausie locks are upside down, but as long as you're using the standard picks for pin tumblers and special warded picks etc for warded locks then they should all work.
don't start on bilocks (which seem to be getting more common) or Abloys (probably find them at uni's and government buildings).
recent lockwoods are not really the best to start picking on either - they're made too well.
I bought my picks from
www.lockpickshop.com (the site's sponsor) if you put in lp101 into the coupon box you get 10% off from your purchase - I recieved my picks within their stated 5 working days or whatever it is.
I would however, in hindsight have chosen the slimline set over the standard set but mostly the standard ones work.
Cheers!
