I have recommended Lionel Taylor at Moorabbin several times and will continue to do so until he retires (he keeps on saying he'll retire but hasn't done so yet !).
You will find him housed in Bini's Advanced Flight Training. His course is most enjoyable and his knowledge is worth every dollar you pay for.
His website is aviationtheory.com.au - give him a call to find out when his next IREX class is.
Solid gold.
