I look forward to seeing the footage then! From memory the store I was aligned with when living in Perth did OW for just under $500 like you said, unsure of what other stores charged. If you like wrecks though, both the Swan and the Perth in Dunsborough and Albany are great dives. Sitting on the floor at 30ish metres. Being back in Adelaide now I really don't go out much locally, but prefer to go to Gambier for the caves/caverns instead. Hopefully you'll be ticketed when I come over to Perth for a wedding later in the year though for a Rotto dive!
