In a rare sighting, a blue whale has been spotted just two kilometres from the entrance to the Fremantle Harbour.

The gentle giant can be seen cruising through waters that are only 10m deep in video supplied to 7NEWS by Whale Watch Western Australia.

In a blog post, the eco tour agency said the guest appearance on Monday was a huge surprise so close to the coastline and the whale may have lost its way.

It appeared to arrive with an inbound tanker and as the tanker dropped anchor he continued to move along the shoreline close to Fremantle harbour.

“After our smaller juvenile last week we were delighted, along with our guests, to discover a large adult cruising the waters across the entry channel in Gage Roads,” posted to its Facebook page.

“We travelled with our new found friend out to Stragglers Reef where we let him steam off into the distance and thankfully he didn’t continue south east into Cockburn Sound of water but safely navigated back out to sea.”

Blue whales are the largest animals to have ever existed and can grow up to 30m long. They are known to visit the Perth Canyon to feed on krill.

They undertake a yearly migration up the west coast towards the warm waters of he Banda Sea near Indonesia where they give birth before heading back down to waters off Victoria in early summer — an epic 10,000km journey.

It’s believed the whale that visited Fremantle was heading towards the Bonney Upwelling off the coast of Victoria and South Australia to feast on krill.

News of the whale’s visit created a buzz of excitement at the port and people on the tour group’s Facebook page were also excited by the news.

“Wow would have loved to have seen the beautiful blue whale,” wrote one.
