UPDATE: Two environmental activists who suspended themselves from an ANZ Bank in central Brisbane this morning have surrendered to police.

Kristen MacDonald, 27, and Frank Deevson, 24, scaled the building on the corner of Queen and Creek streets about 7am today to protest against the ANZ Bank's investment in the coal industry. They erected a banner at the site which read: "ANZ We pollute your world".

ANZ's Deputy CEO and the bank's sustainability team have now agreed to meet with Greenpeace next week.

Police, who were at the site of the protest all day, helped the activists scale back up to the roof of the building about 1pm, to the applause of onlookers.
