The ‘Listen Out’ music festival in Sydney has seen 159 arrests for drug offences over the weekend.

The event attracted 34,000 festival goers, with 154 charged with drug possession and five charged with supplying drugs.

This comes two weeks after an expert panel was formed, following two deaths from drug overdoses at Sydney festival Defqon 1.  

The New South Wales Premier has ruled out pill testing for festivals, despite experts in the panel recommending the plan.
