The AFL was forced to pour in more than $2 million in additional funding for the Gold Coast Suns in 2015 to cover a bigger than expected financial loss.

Documents lodged this week with the corporate regulator revealed the Suns made a $300,000 loss last year, compared to a $1 million profit in 2014.

However, the Suns annual report showed the AFL contributing $18.6 million in grant funding in 2014, up $2 million from the previous financial year. It also showed that the club borrowed $1.59 million from National Australia Bank in 2015, on a two-year term with a maturity date of June 30, 2017.

The Suns, who many pundits tipped to make the finals last year, slumped to 16th position in the club's first year under new coach Rodney Eade.
