- penicillin was discovered (and given its name) by Alexander Fleming ten years before Florey started working with it. Florey was certainly an Australian - from Adelaide no less - but he got his degree and masters from Oxford (which is where he was employed when he worked on penicillin as a treatment) and his PhD from Cambridge. His research was funded jointly by the UK and the USA, so it's a bit rich to suggest that Australian education gave penicillin it to the world;
- spray on skin for burn victims was developed by Fiona Wood, a doctor who works in Perth. She comes from Yorkshire and was educated in Pontefract and at St Thomas' Hospital in London, before moving over here after she married an Aus surgeon;
- the first example of pre-paid postage is the postage stamp (before that, the receiver had to pay to receive mail), introduced in the UK in 1840 and the reason why the UK is the only country in the world that doesn't put its name on its stamps;
- secret ballot voting was used in ancient Greece and Rome and was introduced in France after 1795 when its constitution ordered that all elections would be conducted that way. It's true that this system is sometimes called 'the Australian ballot' because it was one of the Chartist ideas that the UK parliament wouldn't adopt in the 1840s but did allow for its introduction in Australia in the 1850s.
I'm not having a dig at Aus education - some think it's great, others don't - but such a list as the one above does little to support either point of view. Oh, and don't get me started on differential gears ...
