Police said the incident occurred on January 28 when two women decided to meet up in person after having a discussion in an online group chat.

They allegedly became involved in a physical fight at Brookvale, with two other women from the group attempting to separate the pair.

Police and NSW Ambulance paramedics attended the scene and both women, aged 33 and 36, were taken to Northern Beaches Hospital.

The 36-year-old was treated for a head and shoulder injury and a cut to her arm, while the younger woman was treated for a sore shoulder and other non-life-threatening injuries.

Last week, a post about the incident was shared on the Northern Beaches Police Area Command Facebook page.

"It began with an argument between two women on a mothers' group chat site about the current coronavirus and its effects," the post began.

"From there, the women … agreed to resolve their differences in person …"

Not long after the ABC made inquiries about the post, it was deleted and police did not return calls.

Both women have since been released from hospital and were yesterday charged with affray.

They are due to appear in Manly Local Court on March 25.
