Yarra Bay is also great spot for SW. Had this all to myself and a couple mates many times throughout winter season. Used to be popular with local crew but as many have dispersed by moving out of Sydney or concentrating more on wave riding it has become somewhat unused. It gets a bit gusty if wind moves too southerly or too westerly but in pure SW its a beauty.
Look in the UBD for location or have a look at the map NSWKBA put together in conjunction with Southern Sydney Kiteboarding Club. Ive got some if you see me on the beach or Kitepower has some at the shop.
If you want to use this location regularly its a good idea to join the Yarra Bay Sailing Club as you get parking facilities right at the water and can also use the hot showers etc. after your sess...then you can sink a few cold ones whilst sitting on the verandah overlooking the water whilst you wait for the juicy medium rare T-Bone to come off the grill ... see why I love the place



PS, Its where I learned to ride...never ride alone ... that applies to even the so called safest flat water spots ... there is always the unknown ... you need a buddy covering your back.
