A jet ski rider has scooped up a brick of cocaine floating in the ocean.

Daily Mail Australia understands the video in 's Bondi was captured in early January.

Footage showed the man pick up a brown-taped 'brick' from a storage compartment. The package has the word Zoe written on it.

'So I've just been up between the heads and I've just found this little package. Looks like cocaine,' he said.   

'So we're just about to hand that over to the police.

'Probably $100,00, $200,000 bucks in that little package there - just around the corner off Bondi. So Zoe, you're gonna miss out on your present.' 

The strange find is not an isolated incident.

Up to 213kg of cocaine has been discovered between Sydney and Newcastle since December 22, with 90kg of the drug found in the New Year.

The NSW State Crime Command have employed a marine expert to determine how long the tightly-wrapped packages have been floating in the ocean.

Detectives hope this will shed light on which shipment the drugs belong to, with stamps on the cocaine proving vital clues to which gangs may be involved.

The first barnacle-covered package, weighing about 39kg, was discovered on Magenta Beach, on the state's Central Coast.

In the 48 hours that followed six more packages containing a total of 46kg of cocaine were discovered on beaches between Sydney and Newcastle.

A further 39 bricks of cocaine were found on Boxing Day by a fisherman at Barrenjoey Headland, in Sydney's Northern Beaches.

That same day another 39kg were found at the Newcastle Ocean Baths.

A package containing a kilogram of cocaine was then discovered by a lifeguard on New Years Day, about 1km off North Bondi.

The NSW State Crime Command has taken over investigations into who the packages were intended for and why they're washing ashore.

Police are trying to link the bricks to known importations, with stamps on the packages a key clue as to which gangs the shipment may belong to.

Citizens have been urged not to treat the spate of discoveries as a 'treasure hunt', warning that anyone caught with one of the mysterious packages would be charged with being in possession of a 'large commercial quantity' of narcotics.

'If someone is caught in possession of one of these bricks, it's a large commercial quantity and that carries 25 years to life imprisonment, so its a significant penalty,' NSW Police State Crime Command director Jason Weinstein said earlier this month.

'We don't know what the purity of that is just yet, we don't know what is mixed in with that, there's a whole range of unknowns.'

Anyone who comes across an object they suspect contains cocaine has been urged not to touch or open it and instead contact police.

While some of the tightly-wrapped bricks have washed ashore unharmed, others have been ruined by saltwater seeping through the packaging.

Investigations into how the cocaine ended up on Aussie shores are continuing with theories including the packages being thrown off a cargo ship or being dislodged from an anchor by ex-Cyclone Jasper.
