Ashton Kutcher and Mila Kunis take their love fest Down Under

Ashton Kutcher and Mila Kunis have been seen getting romantic in Los Angeles, New York, and now … Sydney.

Looking no different than your average tourists, the lovebirds have been taking in the sights of Australia's most populous city ever since they arrived on Halloween. Their Friday morning was spent exploring the famed Bondi to Bronte Coast Walk. The hour-and-a-half stroll takes walkers along beaches and parks, while offering stunning views. Kutcher, 34, and Kunis, 29, had on sensible attire for the casual stroll — including jeans, sneakers, shades. They sipped coffee and held hands as they strolled. She even snapped several photos of him with her camera phone.

The day before, they were clearly feeling warm and fuzzy when they decided to visit the Wild Life Sydney Zoo. While there, they didn't seek VIP treatment — they arrived as regular visitors and enjoyed the Python Encounters area, where guests can have a snake draped on them for a memorable photo-op. They also were able to get up close and personal with koalas on the rooftop deck at the zoo. The animal lovers, who have been seen walking Kutcher's dog many times throughout their six-month romance, were "very friendly and enjoyed their visit," said a rep for the zoo. They did however decline to be photographed — though fellow celeb Val Kilmer had no problem posing for a pic a few days earlier. There is a photo of the former "Top Gun" star posing with a koala on the zoo's Facebook page.

The reason Kutcher and Kunis are in Australia in the first place is because he's on a business trip. One of the "Two and a Half Men" star's many side ventures is being an investor in Airbnb, a website offering vacation rentals around the world. The company is expanding to Sydney it was announced this week, and Kutcher hosted a dinner party at Three Blue Ducks, a beachside restaurant in Bronte, which was attended by Spice Girl Melanie "Mel B" Brown, and local celebs including singer Brian McFadden and model Ruby Rose.

Late last month there were rumors that Kutcher and Kunis were expecting a child together, but it turned out that the actress was just suffering from a wardrobe malfunction — her shirt was a little too blousy. A rep for the couple quickly shot down the rumors (and Kutcher is still technically married to Demi Moore), but we wouldn't surprised if it did happen down the road. These two sure do look happy — whether they're loving it up in Australia … or in the good ole U.S.A.
