In the three way reality war between Seven, Nine and Ten last night, it was The Block that again emerged victorious.

The show topped Wednesday night in total people with 1.511 million viewers, according to preliminary ratings figures from OzTam. It was also first in all key demographics.

Against it, MasterChef Australia came in second with solid a 1.125 million viewers. This also helped Offspring (906,000) achieve a season high.

With so much reality on offer, Seven's Australia's Got Talent (881,000) and  Amazing Race Australia (695,000) both struggled.

Next week The Amazing Race Australia moves to a new Monday 7.30 timeslot in a bid to increase ratings now that Nine's ratings juggernaut The Voice has vacated the slot.

Nine's strong performance saw it take out the night in both primary (23.2%) and network (28.4%) shares. Seven came in second with a network share of 26.8%, followed by Ten (22.7%), ABC (16.2%) and SBS (5.9%).

Following The Block, two repeat episodes of The Big Bang Theory (1.060m, 0.885m) did good business for Nine. The Mentalist scored 671,000 in a later slot but against it, the return of House did not make the top twenty for Ten.

At 6 o'clock Nine News (1.294m) was close behind Seven News (1.302m) and had significant wins in Sydney and Melbourne. This helped A Current Affair (1.228m) manage a national win over Today Tonight (1.075). The Project 6.30 managed 635,000 viewers against its rivals on Seven and Nine. Home and Away (835,000) was fourth in its timeslot.

In the early evening war, Ten News at Five (803,000) defeated Hot Seat (760,000) and Deal or No Deal (655,000).

It was ABC News (906,000) that topped the night for the ABC, however 7.30 (540,000) saw a large drop in viewers afterwards. Myf Warhurt's Nice also made it into the top twenty on 597,000 viewers.

In digital channels, Seven had more reason to smile with 7mate (4.1%) coming in first and 7Two (3.8%) also performing strongly, ahead of Go! (2.8%), Gem (2.3%), Eleven (3.5%) and One (2.0%).

However, it was ABC2 that managed a particularly strong performance (4.0%) thanks to Dumb, Drunk and Racist (266,000).

Despite this, Neighbours (306,000) was again top of the digital channels.

In morning television, Sunrise (375,000) beat Today  (323,000) and Breakfast (31,000). The Morning Show (184,000) also beat Mornings (140,000) on Nine and The Cirle (63,000) on Ten.
