WHEN it comes to white whale Migaloo, there’s only one thing rarer than seeing him once: seeing him twice, on both his northward and southward migrations off the east coast.

Gold Coast whale-watchers have been treated to two sightings of the majestic mammal months apart.

He was spotted off the Glitter Strip on his northward migration in July, and again today as he headed back south to Antarctica.

Tourists aboard the Sea World Whale Watch vessel thrilled to a spectacular display put on by Migaloo off the southern Gold Coast.

“Everyone was pretty excited — seeing Migaloo is a once-in-a-lifetime experience for most people,” he said.

“He was trying to interact with a black whale and put on a bit of a show, which was good.”

Mr Robertson said people often missed out on seeing Migaloo altogether, as he slipped up the Queensland coast under cover of darkness or in rough weather.

“This is the first season we’ve ever seen him on both his northward and southward migration so it’s pretty special,” he said.

“Our crew were almost more excited than the passengers because they realise how rare this is. We’re just so lucky.”

Migaloo is expected to take another couple of months to reach Antarctica.

“He normally travels with an entourage of (whale) escorts but he seemed to want to be a loner today,” Mr Robertson said.
