A one in a million chance encounter with Migaloo the white Humpback Whale as he leaves the Great Barrier Reef, migrating back to Antarctica after spending the worst of the southern hemisphere winter off Port Douglas.

Migaloo under escort as whale watchers get too close for comfort
By Elise Kinsella and Damien Larkins
Authorities are escorting Migaloo the white whale up the south-east Queensland coast after a complaint of onlookers getting too close.
The Queensland State Government is investigating a complaint about people getting too close to the white whale off the Gold Coast.
As white whales are classified as special management marine creatures, boats must stay 500 metres from them, and aircrafts and drones must keep a distance of 610 metres.
Rangers will begin helping to protect Migaloo during his northern migration on Thursday, until he reaches the Great Barrier Reef Marine Park.
Queensland Environment Minister Steven Miles said it was important whale watchers respected the protection zones.
“The last thing we would want to see is for a whale like this to be injured in a boat strike,” he said.
“It’s just so important people keep their distance, especially as we understand there are a number of boats there.”
He said whale watchers could be fined if they went within the protection zones.
“Humpback whales, they are big creatures, they can behave erratically,” he said.
Southern Cross University whale expert Dr Wally Franklin said tourist boats could stress humpback whales if they came too close.
“It’s very important while these whales are in this northward migration not to interfere with their travel, not to get in front of them,” he said.
“You only approach him at a very slow speed, matching his speed; you only come in from the left or right and do not interfere with his line of travel.”
White whale-watching rules:
Boats must stay 500 metres away
Aircraft and drones must stay 610 metres away
Approach whales from parallel and slightly to rear – never from behind or head-on
Move off slowly and leave no wake
Do not get into the water

Thanks for your comment! I personally did not see the white whale Migaloo. But, many years ago, I did see a humpback whale jumping out of the water in the Antarctic.
