Big Brother's first eviction failed to attract more than a million viewers while talent show The X Factor was the clear winner on Monday.

Melbourne mother Sharon Smith was the first housemate told to leave the Big Brother compound on the Gold Coast during the Nine Network's live telecast.

Her eviction attracted 972,000 viewers, on average, according to OzTAM's overnight figures, making it the seventh most-watched show for the evening.

There's no stopping the Seven Network's X Factor, which is in the bootcamp stage, with the show topping the ratings with 1.422 million viewers.

Coming in at No.2 in the ratings was Nine News (1.322 million) followed by Seven News (1.312 million).

Hamish & Andy's Gap Year Asia was fourth with 1.228 million viewers.

The comedy series dominated the ratings when it launched in early July in the 8pm timeslot, however now that Nine has brought the show forward to 7pm to accommodate Big Brother, the duo have lost a few hundred thousand viewers - and it's No.1 spot.

The second episode of Seven's new imported drama series Mr Selfridge fell from the Top 10.

After launching in ninth place last week with 983,000 viewers, the UK drama was 12th on Monday with an audience of 823,000.
