Foxtel bosses are considering adding women from the axed Real Housewives of Sydney to the upcoming fifth season of The Real Housewives of Melbourne.

The surprising news comes as the subscription network plans a major cast shakeup for the season five of the installment, which could see fan favourite Gina Liano exit the series.

Speaking to The Kyle and Jackie O Show on Wednesday, Foxtel's executive producer Brian Walsh said he'd given Housewives producers the task of 'combining the cities' to create a Real Housewives of Australia series.

'I think some of the women from Real Housewives of Sydney are great talent and we'd love to have them back on the screen,' he said.

'If you think about Krissy Marsh and Nicole [O'Neil], there were some great women on the Sydney show.

'I think there's a way we can get them back on the screen, that's the plan.'

He also said that all the women from Melbourne wouldn't be back, and that there would be a major 'shake up' to stop the show from becoming predictable.

When host Jackie 'O' Henderson asked if Gina would be back, Brian hinted that might not make the cut.

'Last season, Gina said that she would not come back to the show if Sally [Bloomfield] was on the series, so that's taken us some time to see how we move forward,' he explained.

'Gina's an important part of the franchise and we'd love to see her back, but we can't have a situation where the talent is dictating the creative on the show.'

He later added: 'I think it'll be fun casting and I hope that we can uncover some great new faces.'

The Real Housewives of Melbourne is set to return for its fifth season in 2020.
