Well done, mate.
I went to spot X in the logan too. But my timing wasn't as good as yours. The prawns had thinned out in the afternoon. I only managed 1 litre. ( with a crappy bcf net too).
2 days beforehand I managed a couple flatties with my net, as well as 4 litres of decent prawns.
I almost forgot- I snagged 5 John Dory's in one cast at the Rocks close to the pergola ( tossed them all back in). I 'm going early tomorrow!
