Jim,
If you are still a begginer i would suggest RYE front beach/ Rosebud as it is pretty shallow and you can stand for about 200m out, lots of flat water.
Westernport ( peninsula side ) is pretty good in most Easterly directions but not really suitable for beginners as :
1) there is rarely anyone else there
2) not shallow and therefore deep water relaunches are required.
3) its pretty rocky in places.
Once you are confident it is an awesome spot to kite as well as Flinders backbeach and a great break from the crowd.
Just dont tell everyone !
