Deakin psychology research fellow Dr Boxco Rowland said there were high rates of underage drinking in Mandurah and youth faced serious dangers.
‘When asked where they obtain their alcohol, they commonly reported getting it from home, but in some cases from bottle shops,’ he said.
‘The earlier a young person starts using alcohol, the more likely they are to experience injuries and harms, impaired brain development and alcohol problems later in their life.
‘The evidence is very clear ” in communities where underage youth find it difficult to obtain alcohol, there is less youth alcohol use and fewer alcohol related injuries, assaults and deaths.
‘Communities with less youth alcohol use also have higher rates of school completion.’
Dr Rowland urged adults not to supply alcohol to under-18s.
