Tribe - hi- for specifics open the WHERE TO KITE in SEQLD sticky at the top of this forum goes to google map. expand the list of locations (left hand side)
The down winder start stop points and brief description are in yellow. click on the one U r interested in and it zooms in. When I set this up 3-4 years back it allowed a satellite view too which I really like but at present it is just the map. Kemp90's magazine article expanded on these for good detail and colour.
Be wary of the GOkid's casual references to huge downwinders - he is a downwind head banger

(wish I was too!!) and probably training for one of those epic holidays offered in N. Brazil which sound fantastic.
On the Sunny coast, as a rule of thumb the N to S runs tend to be smoother better conditions than the S to N but both are fun. At the extreme low and hi tides it can be a bit dumpee. The time frame for the same run can differ a lot. Mostly due to how you track. If you concentrate on the wave zone and in then it is often 1/2 the time compared to running from shore out to the shark nets and back. That is dependent on what stage you are at = experience.
