A woman has died after collapsing at a netball game in Berkeley on Saturday afternoon.

The 27-year-old, believed to be a Fairy Meadow player, fell to the ground at Fred Finch Park around 2pm.

Two off-duty paramedics at the scene began CPR, before NSW Ambulance crews arrived and continued treatment for cardiac arrest.

She was taken to Wollongong Hospital, where she later died.  

It is unknown if the woman had a pre-existing medical condition.
