G'day
Try contacting Jim Scott. He lives up that way and I am sure he'd be happy to have someone to kite with around Mornington.

Cheers

I second cabstars comment.... in a Northerly head to Rosebud or Rye flat shallow water perfect for a noobie ( you dont have to keep dragging upwind when you lose your board as you can just stand and walk also make relaunching your kite much easier when learning ie: being able to stand ).

In a south west Mt MArtha and sometime Dromana can work although Mt MArtha can be a bit tricky for a noob with deeper water and a very narrow beach down wind.
