Climate activists target PM's NSW office

Protesters are scaling streetlights outside the prime minister's electorate office in Sydney and hanging up a banner to highlight coral bleaching on the Great Barrier Reef.

"Turnbull's Legacy: bleaching - brought to you by Malcolm's mates in the coal industry," reads the banner being unfurled by activists in Edgecliff on Friday morning.

"The best way to protect the reef from the impacts of climate change is to put a stop to the mining and burning of coal and ensure it is kept in the ground," Greenpeace Australia Pacific reef campaigner Shani Tager said in a statement.
