Deep Impact
At more than three hundred and sixty billion dollars, the cost for Australia to acquire a fleet of nuclear-powered submarines is beyond substantial. For the money though, the country will get enormous firepower in the form of the most advanced, and lethal, fighting machine humans can build. The politicians who engineered the deal through the AUKUS security pact say we will also obtain something that's impossible to put a price on: stability in our region. China definitely doesn't agree, but the theory is that by showing our fighting capability, Australia is really proving how much we want peace. But what are these submarines really like? On 60 Minutes, Amelia Adams is given very rare permission by the United States Navy to go aboard and test drive one of its incredible attack subs, the Virginia Class USS North Carolina.

The Year of Living Cheaply
The belt-tightening endured by the majority of Australians over the past year has caused enormous hardship. Finally though, last Wednesday, there was a glimmer of hope when the latest inflation number turned out to be lower than expected. It means there's less chance on Tuesday that outgoing Reserve Bank governor Philip Lowe's parting gift to the country will be a thirteenth interest rate rise. It's a small mercy for many, but for other cash-strapped mortgage holders and renters it's already too late. And also adding to their economic misery, Tara Brown reports that financial experts are now saying much of this cost-of-living pain could and should have been avoided.

Gone Girl
On 60 Minutes, startling developments in a confounding 30-year mystery, the disappearance and likely murder of Revelle Balmain. Back in 1994, Revelle, then 22, was making a career as a model and dancer but she was also keeping a secret. To earn extra money she worked as an escort. When she vanished one night in November that year suspicion fell on her last client, the last person to see her alive. At the time there wasn't enough evidence to bring charges, so the case gathered dust until a fresh team of detectives was assigned to investigate. Now they reveal a major breakthrough. As Tara Brown reports, they've uncovered new clues and new persons of interest. And for those who knew and loved Revelle, that means there's finally genuine hope for long-awaited answers.

What Were They Thinking?
One-time sitcom actor and well-known devotee of Scientology, Danny Masterson, is now also a convicted rapist. Last week he was jailed for 30 years for drugging and sexually assaulting two women in 2003. Masterson's trial attracted enormous attention, not only because of his fame and violent crimes. The Church of Scientology was also condemned, accused of going to extraordinary lengths to protect its star recruit from prosecution. But what's been revealed since Masterson's sentencing is causing more controversy. The disgraced actor received substantial support from fellow Hollywood celebrities including Ashton Kutcher and Mila Kunis. In letters to the judge asking for leniency for Masterson, the married couple described their friend more like a saint than a sinner. They said he was a role model and an exceptional character. Not surprisingly their comments have caused outrage.
