IF WE are to learn anything from events of the last decade, then parents need to be warning their kids of the dangers of swimming in the old disused mines of Swanbank and Collingwood Park.
Many of us who grew up in Ipswich will be able to relate to this.
I was among the scores who used to ride their bikes out to the lake at Swanbank to jump off the cliffs and go fishing.
That was more than 20 years ago, but not much has changed in that time.
At this time of year, in Ipswich, there is always going to be the temptation.
While there is an ongoing campaign to backfill the dams and remove the temptation, any attempt to do this is not going to happen quickly.
Kids being kids, they are not going to be overly deterred by this latest tragedy either.
There is a certain amount of mystery surrounding the circumstances of how three people - and now possibly a fourth - have come to drown in the lakes over the last eight years.
As we've seen in the past, even fit young people that are strong and confident swimmers can disappear.
The warning signs are not enough. The potential danger is something parents really need to drill into their children.
