Zegrahm Expeditions is offering travel advisors a 5 percent bonus commission when making new bookings on select 2019 small ship expedition cruises to Europe and Oceania.

Applicable on new bookings made now through June 30, 2019, select expeditions with bonus commission include the Underwater Wonders of Western Australia and the Best of the Baltic itineraries, plus the Papua New Guinea expedition cruise.

Especially appealing for snorkelers and divers, Zegrahm’s Underwater Wonders of Western Australia expedition takes travelers aboard the 65-passenger Coral Discoverer to explore remote islands and reefs with colorful hard and soft corals, along with healthy populations of tropical fish. Highlights include exploring Ningaloo Reef, the seasonal feeding ground of whale sharks, dolphins, dugongs, manta rays, and humpback whales; visiting Little Turtle Island, an important nesting place for the threatened flatback turtle; and learning about Western Australia’s heritage while visiting Aboriginal rock art sites and an early 20th century whaling station. Pricing for this 15-day journey departing May 13, 2019 starts at $14,580 pp.

Departing on July 4, 2019, travelers will explore eight countries on Zegrahm’s comprehensive Best of the Baltic itinerary. Highlights of this cultural expedition include strolling through ancient squares and villages; opportunities to admire a variety of architectural styles; and exploring myriad landscapes—from the capital cities of Helsinki and Stockholm to the wildness of the Turku archipelago and Bornholm Island. Along the way, guests visit bustling markets and museums, including advanced entry and a special guided tour of St. Petersburg’s Hermitage Museum with access to the Gold Room. Pricing for this 15-day journey aboard the 95-guest Serenissima starts at $13,480 pp.

On the Papua New Guinea expedition cruise, guests can expect to sail aboard the 100-passenger Caledonian Sky as they explore the region’s smaller, outlying islands—some of them so remote, they are only accessible by air and sea and are rarely visited by the outside world. While on these islands, guests will witness the fire dances of the Baining tribe; snorkel or dive among tropical fish and colorful corals; and step ashore on the Trobriand Islands for beaches and tropical landscapes. Pricing for this 17-day adventure, departing on Sept. 20, 2019, starts at $13,980.
