Australian swimsuit model Natasha Oakley shows off her bikini for the day on Sydney’s Bondi Beach. Natasha Oakley has more than 400,000 Instagram followers – and with good reason. The twenty-something Australian model and blogger showed off her impressive bikini body as she enjoyed a sunbake and swim at Sydney’s famous Bondi Beach this week. Oakley is one of the incredible bodies behind the hugely popular Instagram account A Bikini A Day which she shares with fellow model Devin Brugman. The guys in the office are so jealous that I got to post her pictures in this sexy black bikini. They’re all drooling.
