Australians continue to live down to our expectations

This appears to be an Australian re-make of 'Ruthless People", but with unrequited explosions:

About 1am on February 1, 2015, Yarnton woke in the passenger seat and heard a "hissing sound" coming from an open gas bottle in the car, and found his socks soaked with petrol.

Haven't we all woken up like that after date night?
I am just puzzled that the accused Mrs Yarnton -- a "high-ranking police officer" -- could not find more competent criminals than "Married couple Monique Hayes, 25, and Fady Houda, 24" to dispose of her husband.
