Hey there, I'm a Jam instructor from Sydney - I teach mainly at FF St Leo's and Walker St, but am about to hit the pits for some R&R.
My recommendations are to hit any classes that Amanda B (or Breen) is teaching - usually Market St, Park St (and of the city clubs) as well as Randwick. She is one of the Aussie trainers and is probably one of the best instructors in the country.
Also hit up Sean, Tracy or Gayle - their classes are pretty awesome aswell!
Hope this helps, and if you do end up in one of my classes - come say HI!!
