The winners of this year's Triple J Unearthed competition have strongly rejected allegations of misconduct made against one of its members.

Leah Romero, from Melbourne punk quartet The Football Club, published a Facebook statement on Monday afternoon announcing she was leaving the band in light of the allegations.

"These allegations are incredibly serious and though [they] have been vehemently denied, I will still be departing from the band," she said.

"I believe that ... everyone involved need[s] to focus on resolving this situation through the appropriate channels, and that the band comes completely secondary to this."
