Hey guys. Time for an update.
The great news is I have my board in my possession 3 months after loosing it, the condition is exactly the same as the day I lost it.

To cut a long story short, I found the add on gumtree. I simply gave the guy a text saying I was a beginner and looking for a good flat water board.
He said it was a top of the range board and the best one in the shop, he then sent me a text saying he was happy to drop it to 270. I didn't even ask for a discount. Suspect much??
I asked for a few pics as I new my board had cardboard pads and fins, he sent them across in about 2min.... That was my positive identification.
I said the board looks good and can I grab your address and pick it off you tonight when I fly back into Perth? He response was, I'll get my dad to give it to you...
Before I flew back to Perth, I called him and told him it was my board, ect.
He then told me straight out over the phone( I beleive him) that it was his mates board, and this mate dented his car by accident and as payment gave him the board.
I said he should have a word with his mate, that's pretty dodge thing to do.
He then told his old man thr full story and I picked thr board up tonight. Very happy, oh and yes, I gave him a carton of James Boags Premium.
