Lunch at former flying boat base in Perth

Lunching at the "Matilda Bay Restaurant " in Perth, I noticed there was a "Catalina" function room. A sign on the wall indicated this was a former US Navy flying boat base in World War 2. The restaurant is on the banks of the Swan River, across the road from the Nedlands campus of the Unviersity of Western Australia. This was also the original location for the Australian The Double Sunrise service operated between Austrlaian and Ceylon by the RAAF and QANTAS. Unfortunately a sign in the park commemorating this shows a photo of a biplane flying boat (not a Catalina).
