The coroner’s inquest into the fatal Sea World helicopter collision has heard harrowing testimony from the families of three tourists who died in the crash.

The emotional statements, which left the coroner visibly affected, detailed the profound and ongoing impact of the loss on the victims' relatives.

The incident involved a mid-air collision that claimed four lives in total.

The operator, formerly known as Sea World Helicopters and now trading as Surfers Paradise Helicopters, has since implemented a comprehensive suite of new safety controls in response to the tragedy, according to previous inquest hearings.

Earlier proceedings revealed serious concerns regarding operational compliance.

Evidence presented suggested that proper passenger registration procedures were not followed at the time of the crash, raising questions about accountability and adherence to maritime safety requirements during emergencies.
