CAPTAIN Cook Cruises' Sydney whale watching pre-season sale offers up to 50 per cent off whale watching cruises between May 20 and June 30.
The sale brings the cost down to $39 per person (normally $79) and bookings must be made before May 19.
The open-water cruise takes passengers past the Sydney Opera House, Fort Denison and the beautiful eastern suburbs, before passing through the Harbour headlands.
Once in open water the excitement begins as humpbacks are often spotted visiting Sydney's coastline as part of their annual migration.
On occasion, southern rights, orcas and minke whales can be seen, as well as seals, albatross and fairy penguins. Dolphins nearly always accompany the cruise, with some pods numbering up to 100 individuals.
According to ecological consultant and Captain Cook Cruises marine commentator David James, 2017 looks set to be another great whale season.
The company operates whale watching cruises throughout the whale watching season, which runs from May 20 to November 1.
With more than 95 per cent whale sighting success, every passenger has the guarantee that if a whale is not spotted, passengers can cruise again for free.
