She was only announced as a Real Housewives Of Sydney (RHOS) cast member on Friday, and Athena Levendi's claws were already out for her fellow Real Housewives Of Melbourne (RHOM) co-stars.

Speaking to the Daily Mail Australia at the launch of RHOS at the Park Hyatt in Sydney, the jewellery designer described her Melbourne counterparts as 'retired casino waitresses'.

'We Sydney women are so prepared,' the mother-of-three cheekily said.

Claws are out: New Real Housewives Of Sydney cast member Athena Levendi says her RHOM co-stars 'lack decorum' and 'look like retired casino waitresses'

'It's like going on a race with someone who has never exercised in their life. We are like thoroughbred athletes. Like, look at us.

'The Melbourne housewives to me look like retired casino waitresses.

'They lack decorum,' she concluded with a laugh.

RHOM cast: (L to R) Pettifleur Berenger, Lydia Schiavello, Chyka Keebaugh, Jackie Gillies, Janet Roach, Gina Liano, and Gamble Breaux

No drama: Athena also admitted that she didn't want to cause any conflict on the reality TV series, which will begin filming in September

Despite her harsh comments towards the Melbourne women, Athena admitted she didn't want to cause any conflict on the reality TV series, which will begin filming in September.

She said she wanted to 'inspire people' and show them that conflict and profanities wasn't always the best way to mend a broken relationship.

'I'm more of a softer character in the sense that I wouldn't go out seeking to harm them. I'm not prickly, I'm not abrasive and I'm not rude.

She won't be told: The jewellery designer said she won't let trolls get to her

'Sometimes confronting someone with something that has moved you in a sad way and delivering it in a kind way can actually impact and get your message through in a more powerful way than if you sit there and say profanities.'

Athena also won't be battling keyboard warriors if her social media were to ever be trolled.

'[Everyone seems to have an opinion] we are fat, too tall, too busty or not busty enough,' she said.

Inspirational: The mother-of-three said she wanted to 'inspire people' and show them that conflict and profanities wasn't always the best way to mend a broken relationship

'Others opinion is not our business and when you seek to make an opinion your business then you are setting yourself up for a lot of pain.'
