LEE DALTON remembers the moment early on Australia Day in 2010 when she asked to go to the local hospital.
Her "gorgeous" son, Will Dalton-Brown, 19, was fighting for his life.
He and his girlfriend, Eliza Wannan, had been run over by a ute driven by a 17-year-old on L-plates at an alcohol-fuelled Australia Day party.
The two had been asleep in a swag behind the Ford Falcon when the driver backed over them. They both died a few hours later.
About 100 teenagers had been at the party, many under-age and drinking alcohol on a property near Molong. They had permission to hold the event, organised by a local teen, from the property's adult owners.
The ute driver had reportedly been drinking at the party, though he was never charged with any offence.
Ms Dalton, a solicitor from Orange, has backed the O'Farrell government's move to tighten laws around the supply of alcohol to under-age drinkers.
While she believed parents should be able to make decisions on their own children's alcohol use if they drank in a moderate and responsible manner, Ms Dalton said there should be laws governing the supplying alcohol to minors.
"Parents and guardians who knowingly provide party venues for children under 18 years of age, knowing under-age drinking will take place, should be legislated against," she said.
"Parents and guardians who knowingly provide a venue for binge drinking for children under the age of 18 years and young adults should be legislated against."
She said if licensed venues were required to practise the responsible service of alcohol, so too should private functions and parties.
"These irresponsible parents and guardians are not only putting their own children at risk, they are potentially placing at risk every other partygoers' health, their reputations and in the worse possible case scenario, their lives."
