After Real Housewives Of Sydney premiered this year, it made the previous three seasons of its Melbourne rival look tame.

But following the release of a truly epic trailer, Real Housewives Of Melbourne looks set to air the most explosive season of reality TV Australia has ever seen.

In just over a minute, Wednesday's season 4 clip managed to tease adultery, all-in brawls, a brutal black eye and the crowning of a new 'queen.'

Explosive! Following the release of a truly epic trailer, on Wednesday, Real Housewives Of Melbourne looks set to air the most explosive season of reality TV Australia has ever seen

By far the most intense moment captured was an intense exchange between Janet Roach and a worked-up Jackie Gillies.

Shot at a crowded restaurant, Janet could be heard trying to calm Jackie down following an altercation.

'Just calm down Jackie!' she begged to no avail.

Painted with a determined stare and towering over her cast-mate, Jackie fired back; 'when someone f**ks my best mate, I don't do that (calm down).'

Biggest yet: In just over a minute, Wednesday's season 4 clip managed to tease adultery, all-in brawls, a brutal black eye and the crowning of a new 'queen'

The clip then cut to a shocking aftermath: a frail and petrified Janet, leaning on another housewife just to stay upright.

Cameras zoomed in to show the 58-year-old with a huge, swollen black eye, as she appeared to be on her way to hospital.

While the trailer made it look like the shiner came from a fight with Jackie, it's clear the footage was shot at a different time and edited together.

Speaking to Daily Mail Australia however, Real Housewives Of Sydney's Lisa Oldfield confirmed: 'The black eye was definitely inflicted by another housewife, let me tell you that!'

The trailer began by documenting a fiery initiation for newest housewives Sally Bloomfield, 52, and Venus Behbahani-Clark.

Brought in following the shock exits of Pettifleur Berenger and Susie Mclean, Sally learned her place in the pecking order just seconds after meeting the group.

'What planet have I landed on,' she asked early on, a question that was immediately shut-down by a fiery Gina Liano.

'You've come into this group, and whoever you think you are, I'm not interested,' she offered, leaving Sally eating humble pie.

Gina looks to be on the war path this season, with the trailer coming to a close on another shocking claim from the 51-year-old.

Seen at a dinner party, an off-screen housewife could be heard yelling at Gina: 'don't play the victim card!'

Standing away from the rest of the group and with her arms folded, she fired back: 'I'm not the victim, I'm the f**king queen!'
