2 ways for you to start the way up
First try and get a hold of Debbie she use to be manager/proprietor of the Gold Fields Bowl
She is a very experienced bowler and would have loads of advice and coaching tips to pass on. I'm sure someone at the centre there would know how to get a hold of her
The other way is to get yourself on video taking all angles.
Once you have done that I can recommend a few coches in Perth who I know would take the time and watch the tape and offer correspondence.
I knew of a guy many moons ago doing this, he bowled up in Cairns and use to send tapes over to Perth for Gary Gilmour to look at.
Either post me in here or feel free to email me from the link above
GOOD LUCK
