The trial for the Australian couple who allegedly imported cocaine, methamphetamine, arms and ammunition will begin in the Suva High court today.

Yvette and John Nikolic were charged after drugs, arms and ammunition were found on their yacht in Denarau, Nadi last year.

State amended the charges and introduced two alternative counts.

The two are jointly charged with two counts each of importing an illicit drug with two alternative counts of possessing an illicit drug.

They are also charged with a count each of possessing arms and ammunition without holding an arms license.

The couple was arrested after authorities seized 13 bricks of cocaine weighing 15 Kilograms as well as ecstasy tablets with an estimated value of $30 million from their yacht.

Officials also found $30,000 in undeclared currency, guns and ammunition on board.

State has indicated it will be relying on the caution interview during the course of the trial.

Defense counsel did not challenge the use of the caution interview but requested if the interviewing officer could be present in court, as he would like to cross-examine the officer.
