"Enough is enough," Sydney residents are telling future brides and grooms who plan to hold their wedding and reception at McKell Park in Darling Point. The park has become a very popular place for couples to say "I do" that residents elevated the matter to the New South Wales Supreme Court to settle the matter.

The lush harbour setting of the park led about 70 couple to hold their wedding and reception and other important personal landmark events at McKell in 2012.

However, local residents, including media mogul Kerry Stokes, complain that the ceremonies disturb the tranquility of the place and cause traffic because of parked vehicles.

While the Woollahra Council had limited the number of events to two per day on weekends with a maximum of 100 guests per event, residents complained that the council is running the park like a function centre when it should be open to the public.

Although the council ban the use of amplifications and eventually the holding of receptions, residents said there are often violations of the rules on guest limits and noise.

If the court, which hears the residents' petition on Feb 20, would favour the locals, Woollahra Mayor Andrew Petrie said the city would have to cancel booked weddings.

He added even if the locals win the lawsuit, the NSW government would unlikely ban weddings in other state public parks.

It costs couples up to $445 to hold a two-hour wedding rite at McKell. The council sources about 40 per cent of its special events income from the wedding venue rental fees.
