Three Victorian clubs have "made enquiries" about Brisbane Lions star Charlie Cameron, according to Seven News' Tom Browne.

The report states that Cameron is prepared to leave if he can't work out an extension with the Lions.

It is believed that Carlton have launched a "big indicative offer", the Kangaroos are interested and a third unnamed club have made informal inquiries with his management.

Cameron is out of contract at Brisbane at the end of 2021 but is reportedly willing to request a trade to Victoria at the end of the season if a suitable extension can't be reached.

Brisbane and the 25-year old's management have reportedly hit an impasse in negotiations.

Cameron was traded from the Adelaide Crows to Brisbane at the end of 2017 on a deal worth $700,000 a season, according to sources.

The small forward has booted nine goals from four matches this season to sit equal-third in the Coleman Medal race.
