A nearly 11-foot shark was reeled in by two fishermen off Australia's New South Wales coast Wednesday. Photos of the two fishermen were shared on Facebook as they posed with the massive bull shark.

The shark was caught along Georges River at Picnic Point, a beach popular with swimmers in Sydney’s south. Hassan Alameri and Luke Moir told Australia's 9NEWS that it took them about an hour to capture the shark and they sought help from onlookers to pull it from the water.

"It was really hard to bring him up on the sand because he was really big and we had like two or three people with us helping," Alameri said. "We had him on (the fishing line) for about an hour and it took us all the way down the beach — about 250m down the beach."

Alameri said they took photos of the shark before releasing it back into the water.

"I’m all about catch and release — especially (with) a fish like that," he said.

Mac's Bait Bar at Blakehurst, which reposted the first image from a closed Facebook group, wrote: "Caught today picnic point. This time bigger than the last post mid December ... this one 3.5-meter bull. Approx 150 kgs. They are there right under your noses people." 

Andrew Lazarides, owner of Mac's Bait Bar, said several bull sharks had been caught in the Georges River over the last two weeks.

"The others were in the 2 to 2.5 meter range," he said. "There are plenty there — we only hear about a small percentage... They could be anywhere from Captain Cook Bridge right up the back."

Lazarides said the sharks posed a threat as they lurked in Botany Bay and people should be careful before going for swimming in these waters. 

"During broad daylight, swimming is probably OK, but not at dusk or dawn or when they are feeding on bait schools," he said.

Last year in November, NSW Maritime issued a warning after a large bull shark was caught in the Georges River. 

Below are some tips as to how to avoid and survive a shark attack, courtesy of the Florida Museum of Natural History website.

1. Choose to swim in a group as sharks most often attack lone individuals.

2. Don't wander too far from the shore as it may be difficult to return fast for help in case a shark is spotted.

3. Avoid the water at night, dawn, or dusk as sharks are most active at these times.

4. In case of a cut, do not enter the water as blood attracts sharks.

5. Leave the water immediately if a shark is spotted.

6. Avoid going into waters containing sewage as it attracts bait fishes, which in turn attract sharks.

7. Don't splash a lot in the water. Erratic movements can attract sharks.

8. Avoid swimming toward a shark if it's seen in the water.

9. Do whatever it takes to get away after a shark attack.
