M1 Cycles is now your only local dealer for Garmin products.
Now I'm only new to the Garmin scene but, my Garmin "talks" to the node sensor in my Trek frame - so I don't have to have the extra sensor bits etc hanging off the frame (much better bling bling!!!). It also has a lighted display so even in the dark climbing hill circuits I can see how slow I'm going and how much my heart is hurting!!
LG is the guru on the Garmin range - that's why he's called "Lord Garmin"!!!! - so if you need any tech info, LG's the one to harrass!
Check out what's available at www.garmin.com.au and then scoot on into M1 Cycles to score your Garmin.
