Hollywood actress Charlize Theron managed to sneak into Sydney unnoticed last week but her cover was blown when she found herself having lunch only metres away from a table of media on Monday.

Theron and son Jackson had lunch with three friends at Rose Bay restaurant Catalina at the same time as the launch of Foxtel's big-budget History Channel series Coast Australia, attended by Fairfax columnist Peter FitzSimons, TV presenter Brendan Moar and acclaimed Scottish historian and presenter Neil Oliver.

The Oscar-winner is in town for an extra three weeks of filming for George Miller's highly anticipated Mad Max: Fury Road, which finished shooting in Namibia last December. She will reportedly be filming on location.

Wearing denim shorts, a colourful shirt, sunglasses and Roman scandals, Theron bounced Jackson, whom she adopted 18 months ago, on her lap and enjoyed the sun and company at Catalina on Monday.

Theron made waves when she had to shave off her blonde locks for her role in Mad Max: Fury Road.

Adding to the star factor in the dining room of the upmarket restaurant on Monday was Tim Holmes a Court, having his regular Monday lunch session with Sneaky Sound System's Daimon Downey.

Sarah Murdoch sat nearby with her mother and a group of friends that included Vogue editor Edwina McCann.

Theron adopted Jackson from her home country, South Africa, in May 2012.

She recently finished the thriller Dark Places and stars alongside Tom Hardy and Nicholas Hoult in the fourth instalment of the post apocalyptic Mad Max blockbusters. She plays character Imperator Infuriosa.

Mad Max producers decided to reshoot some scenes after initial testing of the film.

The film is due to be released in May 2015, 30 years after Mad Max Beyond Thunderdome.
