Aussie of the Year vows to keep up fight

Australian of the Year Grace Tame is feeling humbled and empowered as she prepares to help educate the nation on child sexual assault in a bid to stamp it out.

The 26-year-old from Tasmania was awarded the top national honour on Monday, having already been named the Apple Isle's Australian of the Year.

A day later, she's feeling honoured and humbled.

"More so than anything I'm feeling empowered and ready to keep going and using this platform to create change," Ms Tame said on Tuesday.

"There's still a lot of gaps in our collective understanding on this issue of sexual abuse, of sexual assault.

"There's a lot of structures in place that still enable predators and don't protect victims. And we need to look at how we can review and reform those."

Ms Tame, along with the three other winners of the Australian of the Year award categories, attended a flag raising and citizenship ceremony with Prime Minister Scott Morrison to mark Australia Day.

Mr Morrison applauded Ms Tame for being an inspiration.

"A woman of immense moral courage and strength - leading the #LetHerSpeak campaign, giving voice to survivors of sexual assault."

Federal Labor leader Anthony Albanese also met the "legendary" Australian of the Year.

"She's using her voice to stand up for survivors of child sexual abuse everywhere. Her strength makes Australia stronger," he said.

Ms Tame was recognised for her tireless advocacy for sexual assault survivors, resulting in the overturning of Tasmanian laws preventing survivors from speaking out.

At 15, she was groomed and abused by her high school maths teacher, who was later jailed for his crimes.

Her experience sparked the #LetHerSpeak campaign, helping Ms Tame become the first woman in Tasmania to be granted the legal right to speak out about her experience as a sexual assault survivor.

Ms Tame has pledged to spend the next year advocating for better education on assault, grooming and psychological manipulation by abusers.

Prominent advocate Patty Kinnersly says the significant of Ms Tame's win for survivors can't be understated.

"This ultimately will contribute to the changing of community attitudes and misconceptions for the better, which is key in preventing violence against women."

Aboriginal elder Miriam-Rose Ungunmerr-Baumann has been crowned Senior Australian of the Year, imploring the nation to better understand Indigenous communities.

Young Australian of the Year Isobel Marshall is a social entrepreneur and student who is passionate about ending period poverty and stigma around menstruation.

Kenyan refugee turned NSW local Rosemary Kariuki was crowned Australia's Local Hero for her work helping female migrants to combat loneliness and uncertainty while settling into new communities.
