Producers have just one day left to have their say on an irrigation pricing review being led by the Queensland Competition Authority.
Initial submissions for the review, which will examine prices for water supply schemes run by Sunwater and Seqwater, are set to close on Friday.
The state government announced the review in October amid statewide concerns about the cost of electricity and water for primary industries.
Dam safety upgrades and the incorporation of insurance costs into water pricing are expected to be two of the more contentious issues on the table during the review.
Queensland Farmers' Federation spokesman Ian Johnson has described the review as a mixed bag, with some schemes likely to feel a small impact and others set to be significantly affected by changes.
Terms of reference released by the Queensland Competition Authority showed dam safety would be a key aspect of the review.
The authority has been directed to present two price options to the government, one incorporating the cost of dam safety upgrades, the other without.
The cost of these safety upgrades could be substantial, with SunWater currently planning a series of 16 dam improvement projects across the state.
There were concerns that dam safety costs and the cost of flood mitigation would be shouldered by irrigating farmers, LNP natural resources spokesman Dale Last has said.
Water services provided by Burnett Water in relation to the Paradise Dam in Bundaberg have been specifically ruled out of the review.
Submissions can be made by visiting the Queensland Competition Authority’s website.
