Australian passport, blue cover with coat of arms

I lost my Australian passport yesterday around 3pm after a quick coffee run near Flinders Street Station in Melbourne, Victoria. It's a standard navy blue passport with the coat of arms on the front and my photo page marked by a tiny coffee spill on the back page. There's a small dent in the bottom-right corner of the data page and a faint pencil signature on the inside cover—that's how I tell it's mine. This passport is essential for an upcoming visa appointment and has a lot of sentimental value because it was my first big post-pandemic trip. If someone found it, please drop it at the Victoria Lost & Found desk near Federation Square or at the GPO on Bourke Street; I’d be forever grateful.
