The Australian Olympic Committee (AOC) is taking Telstra to the Federal Court over allegations its advertisements are misleading and suggest the telecommunications company is a team sponsor.

The AOC said Telstra's marketing campaign "I go to Rio" is a clear attempt to deceive Australians into believing it is a sponsor of the Australian Olympic Team.

In a statement, the AOC said it was unfortunate "some companies try to mislead the Australian public into believing they support the Australian Olympic Team or have an involvement with the Olympic movement when they don't".

"In 2015, Telstra and the AOC mutually decided not to continue their longstanding partnership," the statement said.

The AOC said it was "extremely disappointing" to see the recent Telstra campaign.

"Despite repeated attempts for cooperation, today the AOC has been left with no choice but to seek appropriate legal measures in the Federal Court," the statement said.

Telstra has responded, saying it has a commercial arrangement with Channel Seven over free Olympic content, and has since updated advertisements saying it is not an official Olympic sponsor.

In its statement, the AOC said it was grateful for the support of its true, valued partners and would defend its right to protect them.
