[speary]

Hi, I'm just wondering if anyone can tell me where the good spots for spearfishing are?



I'm using snorkel and hawaiin sling and live on the Mornington Peninsula,



I want to find big fish '40cm+' (is this likely without getting the scuba out/ going deep?)



Any helpw ould be great, cheers,
