History
Trinity Beach is situated in the Djabugay (Tjapukai) traditional Aboriginal country.

The origin of the suburb name is derived from Trinity Bay.

From 1943 to 1944, Trinity Beach was the site of intensive training in amphibious warfare for Australian and American troops in the context of World War II.

Trinity Beach State School opened on 30 January 1979.

As part of Mulgrave Shire, Trinity Beach experienced suburban development beginning in the 1970s, leading to a population of over 2000 by the mid-1980s.

Trinity Beach became part of the new City of Cairns with the amalgamation of Mulgrave Shire into the new city on 22 March 1995.

In 2000, Cyclone Steve, which made landfall in the Cairns northern beaches area near Trinity Beach, caused significant damage to the roof of the Trinity Beach Hotel.

From 2004 to 2008, the 173-ha Bluewater subdivision, which extends through both Trinity Beach and Trinity Park, was approved for development. As with several other areas in Trinity Beach, portions of the estate sit in a flood zone due to potential inflows from Moore's Gully, which led to a substantial flooding mitigation project for the development in 2010.

In 2023, Trinity Beach was affected by Cyclone Jasper and the resulting 2023 Cairns floods. On 13 December, as the cyclone made landfall, the Trinity Beach waterfront experienced a storm surge event, while soon after overnight, multiple waterfront businesses were vandalised and looted.

On the morning of 17 December, like other Cairns northern beaches suburbs, Trinity Beach experienced flooding. This flooding led to an evacuation warning for the Bluewater Estate and major road closures,  which resulted in isolation from the rest of Cairns. Videos on social media soon emerged showing inundated residential neighbourhoods in the suburb. The beach itself was thickly covered with debris in the aftermath of the flooding.
