A virtual petition established a year ago to have the Aboriginal flag fly permanently atop the Sydney Harbour Bridge has entered the real world.

The founder of the popular Change.org campaign, Cheree Toka, led a small protest group on Saturday as the activists marched across the Harbour Bridge calling for the Aboriginal flag to be flown above the iconic landmark 365-days a year.

Toka, a 27-year-old Kamilaroi woman, originally established her online petition calling for NSW Premier Gladys Berejiklian and her colleagues to make the change. It has so far attracted more than 86,000 signatures.

"We want Gladys to recognise Aboriginal voices. She keeps dismissing the issue," Toka said.
