After going relatively quiet for the past two months, climate change activist group Extinction Rebellion is back and planning major Brisbane CBD disruptions this week.

The protesters plan to march from South Bank across to State Parliament on Wednesday before shutting down the Go Between Bridge between Milton and South Brisbane on Friday.

Extinction Rebellion spokeswoman Emily Jane said the group had recharged after a week of demonstrations in October and were ready for their upcoming protests.

"One of the key principals of Extinction Rebellion is our regenerative culture, it is important to look after each other," she said.
