The 31-year-old completed her caption with hashtags: “#Engaged #happytears #kneegotshaky #brokenhill #silvercity #hometowntour #gettingmarried.”
The couple, who met at a Sydney pub in 2016, are believed to have got engaged during a visit to Julie’s New South Wales hometown of Silverton this weekend.
Hugo is a Scottish-born Australian actor known for his roles in dramas such as Rake, Sea Patrol and Underbelly: The Golden Mile.
Meanwhile, Julie made headlines after footage showing Channel Nine newsreader Amber Sherlock berating her for wearing a white jacket went viral.
Amber was also wearing white and slammed Julie for wearing the same colour as her.
“I need Julie to put a jacket on because we're all in white. I asked her before we came on… Julie you need to put a jacket on,” a frosty Amber told their producer.
When their segment went live, Julie could be seen wearing a black jacket over her white dress.
