Retired hydrologist and environmental manager Eric Hatfield, of Kareela, is a close follower of what Hughes MP Craig Kelly has to say about climate change and other environmental issues.
Mr Hatfield monitors the MP's media interviews and social media posts and analyses them on a new website and Facebook page called Hughes Fact Check.
He says the critiques aim to be respectful, with a touch of humour, and as factual as possible, providing links to reference material and other sources of information.
Mr Hatfield had a long career with the state government. He trained as a civil engineer and specialised in hydrology, working to improve the health of the state's river systems.
After several unsuccessful offers to "assist" Mr Kelly with information, Mr Hatfield and some like-minded professionals launched the website on August 23. A Facebook page followed.
Mr Hatfield said the effects of climate change were irrefutable and borne out once again in the findings of the Royal Commission into last summer's bushfires, released on Friday.
An unfazed Mr Kelly said, "It's ironic that something that calls itself Hughes Facts is so choke full of fiction, misinformation and the denial of the facts".
"With the misinformation they are spreading, it looks like they are going to keep me busy having to fact check and correct the fiction they publish," he said.
Mr Kelly said an example was "their denial of the facts of that our hottest days have been deleted from the records".
"The inconvenient truth for them is that Australia's hottest ever day recorded with standard equipment at an official government weather station was 125°F (51.7°C) at Bourke on January 3, 1909," he said.
"This was long officially recognised as Australia's hottest ever day. However, it has since been deleted from the records, and a lower temperature of 123°F (50.7°C), recorded on January 2, 1960 at Oodnadatta in South Australia, has replaced it.
Mr Hatfield responded that all information on his website was from expert sources such as Australia's CSIRO and Bureau of Meteorology, and the US government's NASA and National Oceanic and Atmospheric Administration, with references provided.
He said the royal commission report found last summer's bushfires were "unprecedented" and "climate-driven natural hazards are expected to become more frequent and intense".
Mr Hatfield said he had addressed the hottest day issue on his website.
"The data hasn't been deleted, it is still in the original record," he said.
"But, what are believed to be errors in the data are removed from the analysis.
"The important thing is, this one high temperature record makes no difference to the fact that our climate is heating up, and the hottest years and decades have all been the most recent ones."
