Picture: Twitter Source: adelaidenow RUSSELL Crowe's South Australian mystery has deepened - with his own tweets suggesting he's been "on the back roads to Port Augusta." Earlier it was thought he had flown from Port Lincoln to Port Augusta, but his Twitter entries seemed to suggest a road trip. About midnight, Crowe tweeted: "Some walking, no real exercise. Lots of sweating. Hot. Amazing things on the back roads to Port Augusta. Willy Willy's. Leaving now, to where? At the same time, he gave Del Giorno's cafe/restaurant in Port Lincoln the greatest endorsement it could wish for. I'll give you a travel tip ... Del Giorno's in Port Lincoln, excellent food, excellent coffee," Crowe tweeted. Early yesterday morning, Crowe also tweeted at Scott Grimes (@ScottGimes), an actor who starred with Crowe in the 2010 film Robin Hood, directing Grimes to tweet photos showing fans "where I've been." In the tweet, Crowe says "Don't include stuff about @alanthomasdoyle." Alan Doyle is a Canadian musician, who has performed with Crowe and helped write and produce a number of songs on Crowe's album My Hand, My Heart. Websites suggest a sequel to Robin Hood will be filmed this year and Crowe's travels will have pundits wondering if part of the sequel will be filmed in SA. While the Hollywood star was in Port Augusta, fans got up close and personal at Ian's Western Hotel. Many took photos and chatted to Crowe, who was in good spirits. He was here with a party of six and he was very obliging,' a staff member said. He was happy to have photos taken with people and he looked like he was really enjoying himself. The star complimented staff on his steak meal before heading off with his group. It is not known why he is in South Australia but Crowe told hotel staff he'd be back in Port Augusta "very soon." Crowe's entire trip to SA has been cloaked in mystery, with him being spotted at several locations, but no indication why. On Tuesday, Port Lincoln local Jasmin Buckland was photographed with Crowe outside Del Giorno's cafe. Adelaidenow also understands Crowe was seen in Gouger St earlier Tuesday, after staying at the Intercontinental on Monday night. It is believed Crowe flew out of Port Lincoln on Wednesday on his private jet. That's right Port Lincoln, South Australia, how did you guess? Where will I be tomorrow?
