We should probably be thankful that more of our teens aren't taking advantage of closer ties and cheaper flights and joining the Gold Coast party.
But there are probably enough causing mayhem in our own backyard.
And that's not a new phenomenon. Teens have been getting boozed since the year dot - particularly on New Year's Eve.
Mr Walsh isn't wrong: teens plus excessive alcohol plus no supervision is a lethal cocktail.
And it can be a year-round problem. But the added ingredients of summer holidays, impending independence and the going-away-party factor can be cause for alarm.
Two key messages: 1) Parents should know and care what their kids are up to. 2) Teens should look after themselves and their mates.
Teenagers on the verge of adulthood are at the end and beginning of incredible journeys.
To screw everything up for the sake of a boozy party would be such a waste.
