Lost gold colored nylon pack (Selkirk Trestle area in Victoria)

I left a light nylon pack at the Selkirk Trestle this morning by accident. It is yellowish gold in colour and (I think the brand is Sea to Summit) It contained a Patagonia puffy jacket which is gold/ sandy in color, a blue cycling jersey, a black wool toque and a case containing a pair of clear safety glasses. If anyone found it I would really like to get it back!
