Trinity Beach, one of the more popular Marlin Coast beaches, is 17 km north-west of central Cairns.
Trinity Bay, on which Cairns is situated, was named by Lieutenant James Cook on or near Trinity Sunday, 10 June, 1770.

A fully developed residential suburb by the 1990s, Trinity Beach was a day-long excursion
from Cairns before World War II and a place for weekenders in the early postwar years.
Its growth spurt came in the 1980s when the population increased fivefold to over 4000 people.
Subdivision and development began in the previous decade, when a primary school (1979) was opened.

The beachfront boulevard is Vasey Parade, named after Major General George Vasey, a hero of the New Guinea campaigns
who was killed when the plane he was being carried in crashed into the waters off Trinity Beach in 1948. In 2004 a Vasey Parade
house sold for over $4 million.

Trinity Beach had the first stinger net swimming enclosure..
