Sound of success ... The Voice judge Delta Goodrem.

For the past 18 months, the bruised and battered Nine Network has thrown everything it has at long-time rival Seven but Seven's commanding margin has remained frustratingly out of reach.

But fuelled by The Voice, the most successful new TV show since the launch of Masterchef Australia four years ago, Nine stormed home on the weekend to win its first official ratings week since September 2010.

The victory ends Seven's unbroken 18-month run of weekly wins. Nine had previously laid claim to two narrow wins in 2011, but both were later lost to Seven when "+7" data - that is, ratings collected from homes which recorded shows and played them back within seven days - was added.

Nine won last week with a clear five per cent lead over Seven - a 33.6 per cent share to Seven's 28.6. Ten trailed with a 17.4 per cent share, followed by the ABC (15.4 per cent) and SBS (5.1 per cent).

Nine also won in audience demographics, notably the 25-54-year-old demographic, where most commercial advertising revenue resides. It is also Nine's declared "key" demographic.

Nine also had seven of the top 10 shows for the week, including the three episodes of The Voice and two episodes of The Block.

Seven, in stunning contrast, had only three, though fortunately one of them was its flagship talent franchise, Australia's Got Talent, a hopeful sign that it could build its battered audience in coming weeks.

The Voice storms ahead

The Voice delivered a resurgent Nine Network a series high of 2.69 million viewers last night, but there will be little time for celebration or commiseration: the ratings week is already off to a bruising start.

The Voice's slam-dunk is an early advantage for Nine and a sign this will be another tough week for Seven.

Nine's telemovie, Beaconsfield, a dramatisation of the 2006 mine disaster starring Lachy Hulme and Shane Jacobson, also made its debut last night.

It featured stunning performances from Hulme and Jacobson as trapped miners Todd Russell and Brant Webb, and Michela Banas and Sacha Horler as their wives, Carolyn Russell and Rachel Webb.

It drew an impressive 1.63 million viewers.

Seven ran an extended edition of Dancing with the Stars against both programs in which the show's star recruit, former Nine personality Kerri-Anne Kennerley delivered a leaderboard-topping 27 point dance.

But against the onslaught of Nine's double whammy, Dancing with the Stars drew only 991,000 viewers.

Auditions hit highs and lows

The Voice won decisively, but that was no surprise: the show wheeled out some of its best blind auditions in the series so far.

An audition from Jimmy Barnes' daughter Mahalia Barnes won her a place among the dozen singers Joel Madden has chosen to mentor.

Emma Louise Birdsall also brought the house down with a performance of Duffy's platinum-selling song Mercy which got mentor Seal up, out of his chair and dancing.

But in a dramatic twist, respected singing coach and former Popstars judge Shauna Jensen auditioned as a contestant - unsuccessfully.

"Are you mental?" Jensen asked, when the four judges finally turned to face her, having failed to do so during her performance.

In The Voice's competition rules, when a mentor turns to face a singer during the audition, it is an offer of mentorship. To not do so is considered a pass.

"I think you all made a big mistake," Jensen told the four in no uncertain terms.

Jensen's frustration was compounded by the fact that her daughter Rebecca had performed moments before but was not selected by the judges either.

Following that with a performance of her own was "extremely difficult," she said."The show is supposed to be about the voice," Jensen said later. "Two of the finest voices in this competition just had nobody turn around for them."

The Voice's "blind auditions" conclude this week.

They are followed by "battle rounds" in which the mentors much choose two of their team to sing the same song and, after the performance, choose which of the two will advance to the next phase of the competition.

That process culls the starting 48 to 24, and those 24 will peform in the live performance phase of the competition, which begins next month.
