Suggest you get some more hours. Stay current.
Either as an instructor or something like Flying Doctors in Auz - say around 500 - 1500 hrs and keep applying to airlines.
JAR is v expensive - but why not go on hols to Eire and see if you like it - whilst there knock on some airline doors
Otherwise try MAF or other relief flying organisations like AirServ if you are single and willing to fly in rougher places.
all the best!
