SW Police are warning anyone planning to go to Sydney's Cronulla Beach this weekend that violence will not be tolerated.

A series of text messages have been circulating following two violent incidents at the beach in the past week, including an attack on two lifeguards on Sunday.

Yesterday, a brawl erupted at the beach when a gang of youths allegedly turned on a media crew.

Today NSW Police Assistant Commissioner Mark Goodwin said locals and visitors to the beach should expect a large police presence this weekend.

``I can assure you that if you come down to the Cronulla area ... you're going to see a high visibility of police presence,'' Mr Goodwin told Macquarie Radio.

``We want people to enjoy this beach, it's the best place in the world to have fun and relax ... we're certainly not the fun police but I can assure you we will not tolerate this behaviour.''

While no specific gang related task force had been set up in response to violent incidents at the beach, Mr Goodwin said large numbers of police, including riot squad officers, would be in attendance.

``It's not an officially registered task force, but this is a range of police from a range of specialists areas that will be operating under my command,'' he said.

``I will have down here a large contingent of highway patrol, I'll have our operations support group operatives down here, who handle riot situations, there will be mounted police, there will be dog squad in the area and we will deal with any anti-social behaviour by either side or by any person on the beachfront.''

Police had already charged an 18-year-old and a 20-year-old man over recent violence at the beach, and Mr Goodwin said more people could be charged.

``We've arrested, certainly, two people ... and there may be more to come.

``We've a group of detectives working on that at the moment and I'm ramping that up to include some of our specialist resources down here.''

He warned people not to participate in any vigilante behaviour along the lines of that called for in a number of text messages.

``What we're asking is for the local kids to trust the police and don't ramp it up and escalate it and trust the police,'' Mr Goodwin said.

One message circulating in the Sutherland Shire urges ``Aussies'' to take revenge against ``Lebs and wogs''.

``Bring your mates and let's show them that this is our beach and they are never welcome ...'' the message says.

These are the ****heads who should get deported to wherever it is they claim to come from (no doubt they're all born in Australia and pretend to be 100% foreigner).

Reminds me of the dickheads at Edithvale. Someone needs to take a rocket launcher to that beach and aim just east of the milkbar / shop.

So ... what do you think should be done about these feral lebo homeboys ?

Dirty arabs.... kill em all

Just out of curiosity, which ethnic group are we slandering when we say "lebos"?

Does it matter which is which, Muslim Lebos or Christian Lebos, both same. You get some decent ones in either of them but majority is the same.

k now this convo is going abit too far...

when do generalisations and stereotypes become true?

When you see examples of them all the time.

Unlike alot of eastern suburb types that stick to their own type and live within the confines of their own "safe" and largely homogeneous while-anglo middle class suburbs , I get out into the real underbelly of Melbourne and see what is really going on.

You know what ... before I get some namby-pamby reply , I just want to say ..

I'd rather be seen as a racist than a hypocrite.

no matter where u go or how much u try to enjoy yourself, theres always fcukheads like them cunts in that article like a while ago at edithvale beach girls were relaxing on the grass they told some guys off for doin something to someones dog tied up on the pole, so they bottled her like ratty mofos.

For the benefit of the non Aussie's in this thread.

What are P - Plate drivers?
