Ross Auction for the Jarrah $550 for a pack of 360lm bought two as 10% of the Jarrah was unusable with twists and splits.
The neighbors were a little worried when they saw the posts going up. But once I told them the plan they offered some of left over Jarrah from their patio.
Seems to be doing the trick with the wind, but not had a real test yet with a strong sea breeze. Will have to wait for next summer.
