For those who is looking for a reasonably cheap coach, you may contact Michael Foong. He coaches privately. I was under him for a short time and he improved my ability in singles immensely. I now play at Kellyville club and they boast a number of A and B grade players at times. Majority are Indonesian players and a friend of mine from Malaysia is on par with them. One of them was recently involved in the Trans Tasman Masters Invitational Open in March. The Castle Hill team on Wednesday nights are also quite good.
