Hi Wyn,
Your shark reports is very cool,however I regret to inform you that Pialba Beach is not where you have it. I live locally and the points I'm about to give you are not GPS but from GE.
You have location 25deg.15.33.16S and 152deg 44.19.34E the following are more accurate 25deg 16.38.63S and 152deg50.24.17E. If you fly to "Main St,Pialba in GE then go straight down to the beach, there you have it..
Kind Regards
Cliff
