The 62nd Primetime Emmy Award nominations will be announced 10.30pm AEST tonight.

The nominations for the 62nd Primetime Emmy Awards are set to be announced later tonight and several Aussies in for shot at this year’s announcement.

Toni Collette is a shoe-in for her performance in the dramedy ‘United States of Tara’, which scored her a win for Best Actress in a Comedy Series at last year’s awards ceremony. Collette will likely face similar competition as last year, including ’30 Rock’ star Tina Fey and ‘Weeds’ leading lady Mary-Louise Parker.

Simon Baker, who plays the meticulous Patrick Jane in ‘The Mentalist’, is a hot contender for an Emmy nom in the Best Actor in a Drama Series category, with competition expected to come from some familiar faces – including Bryan Cranston (‘Breaking Bad’), Michael C. Hall (‘Dexter’) and Jon Hamm (‘Mad Men’).

Rose Byrne and Rachel Griffiths are also expected to be up for nominations in the Best Supporting Actress in a Drama Series category for their roles in ‘Damages’ and ‘Brothers and Sisters’.

While the number of Aussies in for a chance for an Emmy nom is fewer than previous years, the number of Emmy upsets is expected to be greater than ever.

TV veteran Edie Falco (‘Nurse Jackie’) and newcomer Lea Michele (‘Glee’) are tipped to compete for the Best Actress in a Comedy Series category, giving our Toni Collette a run for her money.

Meanwhile, Glenn Close (‘Damages’) could be Emmy-less this year, with Juliana Margulies a hot favourite to take out Best Actress in a Drama Series for her role in ‘The Good Wife’.

‘Glee’ and ‘Modern Family’ are expected to turn the best Comedy Series category on its head, pushing 4-time straight Emmy-winner ’30 Rock’ out of its throne.

‘Mad Men’ could also be de-throned with the return of ’Lost’ to the podium for Best Drama Series, in the wake of the show’s sixth and final season.

The nominations for the 62nd Primetime Emmy Awards will be announced by television stars Sofia Vergara (‘Modern Family’) and Joel McHale (‘Community’) at 10.30pm AEST.

The nominations will be streamed live at Emmys.com

Winners for the 62nd Primetime Emmy Awards will be revealed on August 29 on NBC.
