Coalition's Queensland dam bonanza 'threatens Great Barrier Reef'

Malcolm Turnbull's $150m pledge to boost agriculture in northern Australia comes under fire from conservationists

Malcolm Turnbull has promised to spend $150m on dams in Queensland as part of a plan to double the agricultural output of northern Australia - but which would dump thousands of tonnes of pollution on the Great Barrier Reef, according to conservationists.

The prime minister committed $130m to one dam near Rockhampton and a further $20m to feasibility studies for 14 others across the state.
