The Queensland Parks and Wildlife Service (QPWS) is seeking the public's assistance in its investigation into the alleged illegal dumping of asbestos roofing material in the Cherbourg Forest Reserve.
QPWS rangers have observed a number of asbestos corrugated roof panels (commonly called "fibro" or "super six") in the forest, some with the wooden fascia trim still attached.
Some of the wood and roof panels are painted green but most of the material is unpainted.
It is believed the dumping occurred within the past 6 months.
The material was removed by a specialist contractor on Saturday 18 May.
South Burnett Senior Ranger Mark Casey said anyone who may have information about the alleged illegal dumping can report this confidentially to the Department of Environment, Science and Innovation's Pollution Hotline on 1300 130 372, or by phoning the local QPWS office on 13 QGOV (13 74 68).
"Dumping rubbish in any national park, state forest, or forest reserve is illegal.
"In this instance the situation is more critical, as the material dumped contains hazardous asbestos.
"It is also more costly to remove, with asbestos material requiring specialised handling, removal and disposal.
