Invasion Day rallies were attended in record numbers in Tasmania's south and north west on Sunday.

More than 8,000 attended the annual rally in Hobart, crowds marching through the CBD to the state's parliament lawns.

Outside Parliament House, rally attendees heard from councillors, politicians and members of the Tasmania Aboriginal community, who all called for the date of Australia Day to change.

Speakers included Rulla Kelly-Mansell, Nunami Sculthorpe-Green, Anna Reynolds, Nick McKim and Nala Mansell, who said January 26 would always be a day of "mourning, grief, survival and resistance" for Aboriginal people.

"The history of Lutruwita/Tasmania is a sad and horrible history and it's one that this state continues to ignore," Ms Mansell said, the ABC reports.

"We need the country to acknowledge that January 26 marks the beginning of the murder, the slaughter, the invasion of Aboriginal people."

In an act of defiance and while signs emblazoned with phrases including "no pride in genocide" and "not a date to celebrate" were on full display, the Hobart crowd also stomped and clapped in a "minute of power" (rather than a minute of silence) to recognise Aboriginal lives lost at the hands of European colonisers.

"We gather to mourn, to remember, and to remind this country that January 26 is not, and will never be, a day to celebrate, but will always be a day of mourning, a day of grief, of survival and resistance," Ms Mansell told the crowd.

In Devonport on Tasmania's north west coast, more than 100 marched along Best Street to rally at Market Square in the city centre.

There they heard from speakers including Daisy Allen, independent Braddon MP Craig Garland, Uncle Jim Everett-Puralia Meenamatta, who spoke of Aboriginal people's ongoing defence of land and sea Country.

"We need to think about that positive future and get this government to realise that corporate governance is taking us to hell," Uncle Jim said.

"The stands that we've been taking protecting Country, our seas, our waters, and our sky country are ultra important to the environment for human beings to be able to even live here.

"The thing for us to go into the future with everybody, not just us Blakfullas, everybody, is to acknowledge that our Law is in Country.

"And that Law in Country tells us how to behave, how to protect all those resources instead of exploiting them before they are all gone.

"I urge you all to love each other. Because love beats hate."

Writer and producer Adam Thomson told the crowd there would always be "voices seeking to silence us".

"We've marched through the cities, we've carried coffins symbolising the loss and grief felt by our people," he said, the ABC reports.

"But we have truth on our side, and we have right on our side. The fight has always been an uphill battle, but it will go on."
