Prince Charles has wowed the Barossa but it was his wife Camilla who left South Australia with a lasting message, urging more victims of domestic violence to speak out.
The royal couple spent just a few hours in SA on Tuesday, but managed to cram in a trip to two Barossa towns where they thrilled thousands of fans and sampled premium wine and produce.
The Prince also turned the first sod at a sustainable housing development while Camilla took part in round table discussion on family violence along with Australian of the Year and violence survivor Rosie Batty.
The Duchess of Cornwall praised those who were willing to share their experiences of family violence in a bid to shed light on the social scourge.
"It is a difficult thing to report," the Duchess said.
"People sometimes think they're not going to be believed. A lot of people feel shame, so they sit on it for years."
The Duchess told Ms Batty she was "incredibly brave" after she heard how her son Luke was killed by his father last year.
"People think it (domestic violence) is something that shouldn't be talked about, that should be kept under the carpet," Camilla said.
"It takes people like you to speak out about it."
Earlier, the royal couple were greeted by thousands of cheering, flag-waving, crown-wearing onlookers as they stepped out into Tanunda's main street.
They were given a traditional, and useful, Welcome to Country by Ngadjuri Elder Quentin Agius and his grandson Rhashawn, who presented them with a peppermint gum leaf.
"That will come in handy to keep the flies off me," the Prince said.
The Duchess wore a cream and black ensemble made by one of her favourite English designers Anna Valentine and the Prince a light grey suit, perfect for the warm but comfortable conditions.
At nearby Seppeltsfield the royals spent more than an hour talking with winemakers, artisans and food producers and met knife maker Barry Gardner, milliner Julie Fleming and master cooper Andrew Young.
Each presented hand-crafted gifts, including a 20-litre whisky barrel, a taupe-coloured feather fascinator and a Japanese-style kitchen knife.
In the Seppeltsfield barrel room they sampled tawny port put under oak in the years of their birth, 1947 and 1948.
The future king described his vintage as "strong and bold" and the Duchess' as "refined and elegant".
At Bowden, in suburban Adelaide, Charles inspected a green housing project, the Prince's Terraces, a collaboration between The Prince's Foundation for Building Community and residential developer Defence Housing Australia.
The site will host 12 townhouses and apartments using local materials, recycled water and energy-efficient lighting.
Told that a portion of the homes at Bowden would be reserved for low to middle-income earners, the Prince turned to Premier Jay Weatherill and nodded approvingly.
The event was closed to the public but Charles was greeted by a crowd of about 30 devotees.
He couldn't help walking over to say hello and shake their hands - although he politely declined a request for a selfie from a teenage girl.
The royals left Adelaide for Sydney late on Tuesday to continue their six-day tour of Australia.
