Mouth of Brisbane River occurrence

There are already several reports reporting on this case. This one, abc.net.au, is probably the most concise one:

Police say six people have been taken to hospital after their boat was hit with a freak wave near the mouth of the Brisbane River.

Four people were knocked overboard from the 6.4-metre boat during the incident.

Emergency services say three children aged between 10 and 12 are among the injured

The children and one adult were taken to the Mater Hospital, while another two adults were taken to the Princess Alexandra Hospital.

The report covered the where, what, who, and why. But no details about the freaque wave they encountered. It did happened. An unexpected, larger wave capsized the 21 ft (6.4 m) small boat -- most vulnerable to any kind of larger than usual wave actions. Luckily all six people on board, include three 10-12 year old children, are successfully rescued. This is certainly the most important to know. The instant also shows again that freaque waves, large or small, can happen any place and any time. Include the southeast coast of Queensland, Australia. It becomes a worldwide news only when someones encountered it. We don't know how many of them are happening out there at this very moment. No one encounters it, no damages done, so no one concerns, but it just does not mean no freaque wave happenings.
