CAPTAIN Cook Cruises' Sydney is offering up to 45 per cent discount on early whale-watching cruises operating between May 18 and June 30.
The special price is $49 per person (normally $89) but you must book before May 16.
The comfortable ocean-going catamarans with spacious outdoor and indoor viewing areas take passengers past the Opera House and the beautiful eastern suburbs, before passing through the harbour headlands.
Every cruise has a whale guarantee: if a whale is not spotted, passengers can cruise again for free.
Humpbacks visit Sydney's coastline as part of their annual migration. On occasion, southern rights, orcas and minke whales can also be seen, as well as seals, albatross and fairy penguins. Dolphins nearly always accompany the cruise, with some pods numbering up to 100.
Captain Cook Cruises' whale-watching cruises operate throughout the season, which runs until October 31.
Each cruise features expert commentary and a highly skilled onboard team.
The company's marine commentator Michelle Yerman believes 2019 may well set a new record.
"The whale activity is increasing too as more humpback whales migrate through the same stretch of water, resulting in pods travelling closer together," she said.
"This increases the social interaction between the pods, which leads to more spectacular behaviour like breaching, spy-hopping, pec and tail-waving and slapping."
Whale watching cruises operate daily from Circular Quay Wharf 6, departing at 1.30pm and returning at 4.15pm. Additional morning cruises operate on Saturday and Sundays departing at 10.15am and returning at 1pm.
