The Cruise family is currently in Melbourne for Holmes' role in the upcoming horror flick Don't Be Afraid of the Dark.

The celebrity family is staying at James Packer's private Crown Towers penthouse.

They have already been spotted at the theatre, Melbourne Zoo and Aquarium to keep three-year-old Suri entertained.

Tom Cruise also spent his 47th birthday in a corporate box at the MCG with fellow actor Guy Pearce, watching Collingwood defeat arch rival Essendon.

Sovereign Hill has been in touch will the concierge at Crown and staff are putting together a Sovereign Hill hamper full of goodies with a formal letter from Jeremy Johnson inviting them to visit for a taste of Australian gold rush history.

"Over the years Sovereign Hill has played host to many high profile, international guests - from Eartha Kitt and Joan Rivers to the Queen and Prince Phillip," said chief executive officer Jeremy Johnson.

"If the Cruise family choose to visit Sovereign Hill we would offer them the same warm welcome and unique experience that we provide to all our guests."

Meanwhile, 3BA program director Garrath Cockerell said Pink's management hadn't ruled out a visit from the popular singer.

Last month Ballarat was awash with pink as part of a campaign to get the singer to visit while in Melbourne for her Fun House Tour.

The event raised $15,000 for the Ballarat Cancer Research Centre.

Sony representatives have passed on photos and articles from the day, and told Mr Cockerell that Pink was about to take a nine-day break from performing to go on a motorbike tour with estranged husband Carey Hart.

With eight more shows to go in Melbourne at Rod Laver Arena, Mr Cockerell is still hopeful there may be time for Pink to visit Ballarat.
