Inside Bec and Lleyton Hewitt's breathtaking $4 million dollar family home, now for sale.

Bec and Lleyton Hewitt have listed their multi-million dollar Kenthurst property for sale.

The five-hectare property, which has been one of many homes to the couple and their three children Mia, 11, Cruz, 7, and Ava, 6, is expected to sell for $4 million.

The open-plan home in a north-western suburb of Sydney contains seven bedrooms, five bathrooms, a gym and multiple living areas.

Outside there is a pool, a golf green, a playground for the kids and, of course, a tennis court – two actually.

Australia’s sweethearts have owned the property since 2006, but it isn’t the only home Bec, 33, and Lleyton, 35, have owned.

The Hewitts sold their Palm Beach property on Sydney’s northern beaches in 2014 as well as a home in Adelaide.

They have been struggling to sell their penthouse on St Kilda Road, Melbourne since 2011, according to realestate.com.au, recently putting it back on the market.

The six-bedroom home is on offer through Expressions of Interest with a $9 million plus price tag, ending on Tuesday.
