Hi MATMAX
What gas bags said is true, It's got nothing to do with your license being french, Certain Australian agencies don't recognise the EASA license in general whether british or french or whatever CAA it came from.
They are due to recognise it in the future though since CASA and EASA will close ranks but for now and before you consider JHAS make sure that they recognise EASA licenses.
