A "stunning, unique, quirky soul with a caring nature" — that is how mourners have remembered Tasmanian woman Madison Lyden, who died in New York City earlier this month after being hit by a truck.

More than 700 people attended the funeral for the 23-year-old which was held at the function room at Bellerive Oval.

Madison's sister Paige spoke of her heartbreak of losing her twin.

"To be born as a twin is a gift and to be born as Madison's twin is the greatest gift of all," she said.

Madison's mother Amanda Berry remembered a curious person who loved adventure.

Her father Andrew Lyden described the pain of losing his child.

He praised his daughter's academic achievements which included an honours degree in psychology.

"I, as a father, am so incredibly proud of all she's achieved in 23 years," he said.

Partner Rhys Bischof spoke of Ms Lyden's zest for life.

"I'll never forget your bright, beautiful eyes … for standing up for what you believe in," he said.

The service heard of Ms Lyden's love for travel and her kindness.

She was travelling with a friend when she was killed and had planned to return to Australia to complete a masters degree.

One hundred white balloons were released in her honour at the oval.
