Agricultural groups are under fire for not providing enough information to the State Government so it could properly assess how farming practices are affecting water quality on the Great Barrier Reef.

This week the Queensland's auditor-general released his latest report on how well Queensland is meeting water quality targets in reef catchments.

The report found the Government was doing a better job at coordinating its approach, but progress was slow and targets under the Reef 2050 Long-term Sustainability Plan were unlikely to be met.
