Coalition MP Warren Entsch has backed a plan to bulldoze 2000 hectares of pristine forest near the Great Barrier Reef despite being appointed to a role championing the natural marine wonder.

Prime Minister Scott Morrison appointed the veteran Liberal MP, who represents the seat of Leichhardt in north Queensland, as special envoy to the Great Barrier Reef in last month’s ministerial reshuffle.

Mr Entsch once owned Olive Vale station, a large Cape York farm north-west of Cairns, and has been a vocal proponent of land clearing on farming properties in north Queensland. Land clearing can create sediment and nutrient run-off and is the main driver of serious water quality problems on the Great Barrier Reef.

Liberal MP Warren Entsch is a strong advocate of land clearing, despite the possible effects on the Great Barrier Reef's water quality.

In particular, Mr Entsch lobbied his government on behalf of a highly contentious proposal to clear 2000 hectares of forest at Kingvale Station on Cape York Peninsula.
