Estranged wife of ex-Parramatta Eels boss pleads guilty to injuring four while driving drunk

The estranged wife of former Parramatta Eels CEO Denis Fitzgerald has pleaded guilty to injuring four people, while driving drunk in Sydney's Kellyville last year.

Lisa Mottram had been drinking with a friend at the Fiddler in Rouse Hill on September 16.

Court documents show she was captured on the bar's CCTV walking into a pole as she became more drunk.

She was helped from the venue by a friend who dropped her at her Melrose Park home around 6.42pm.

Later that evening, she claims she wanted cigarettes and left her home in a white Honda CRV.

Police say she was travelling to meet a man she was intimately involved with and was texting him as she drove.

Neighbourhood security cameras show Mottram's vehicle swerving as she drove north along Hezlett Road.

Sometime after 9.19pm, the 4-wheel drive left the road, mowing down a family of four who were visiting Sydney from Hong Kong.

Paramedics arrived to find all of the victims lying unconscious on the grass.

A four-year-old girl sustained such serious injuries to her brain and lungs, and has not regained consciousness.

The child was flown by Care Flight to Hong Kong in November where she is being treated in hospital.

The girl's 55-year-old aunt is paralysed. Doctors say it's unlikely she will regain control of her lower limbs.

Now back in Hong Kong, friends say the family is struggling to cope.

The child's father is battling to recover from the lasting effects of a head injury which has changed his behaviour and affected his emotions.

Mottram's blood alcohol was found to be twice the legal driving limit when tested by police.

Detectives say she sent a final text to the man she was traveling to meet just two seconds before the near-fatal crash, a claim the hairdresser denies.

The case will return to court in June.
