Arrests made as SA schoolies let down hair

Police have already arrested nine people at schoolies festivities in South Australia.

One person was also taken to hospital after allegedly taking ecstasy, police say.

And two teens were arrested for allegedly possessing the drug for sale at the Victor Harbor Schoolies Festival on Friday night.

Seven other people, including one non-schoolie, were arrested for behavioural offences.

"While the majority of school leavers are well behaved and are enjoying the festival, I want to warn the public to be aware if you decide to take illicit drugs, you are putting your life at risk," Hills Fleurieu police superintendent Rob Williams said.

It came as thousands of school leavers began arriving on the Gold Coast for celebrations in the traditional NSW schoolies hot spot.

Queensland police said no schoolies were arrested or fined overnight although 16 non-schoolies were arrested on public nuisance and order offences.
