I believe you. like @Restyle said, last year I saw about 8 of them cruising in a pack at the boat ramp in Panania right up close. they were just swimming up and down about a metre out from the bank...I ran home to get my rod (I don't live too far from there) but by the time I got back they were gone. there was tiny bait everywhere that day and they were gone as well when I came back with the rod.
today I was a the park next to the woronora boat ramp for a 3yr olds bday and the water was teeming with bait fish and I saw a huge splash...again I was without my rod, only this time my wife was rolling her eyes at me 😅
