In 1997 she switched from researcher to environment manager with the Queensland sugar industry. In 1998, Marohasy received a PhD on the biological control of weeds. In 2001, she started to develop an interest in environmental campaigns and, in particular, claiming that there are anomalies between fact and perception regarding the health of coastal river systems and the Great Barrier Reef.

Institute of Public Affairs While head of the Environment Unit at the Institute of Public Affairs, Marohasy compiled a backgrounder titled Myth and the Murray - measuring the real state of the river environmentJennifer Marohasy, IPA Backgrounder Vol 15/5, December 2003,Myth and the Murray - measuring the real state of the river environment which was published by the Institute in December 2003. The Institute received a $40,000 donation from Murray Irrigation Limited at that time.ABC Local Radio, VIC Country Hour, 04/06/2004, Institute of Public Affairs accepts irrigation funds. This paper is quoted in the Interim Report of the Inquiry into future water supplies for Australia’s rural industries and communities of the House of Representatives Standing Committee on Agriculture, Fisheries and Forestry, March 2004. At a science round table of the committee, when asked for her views on how much water should be returned to the River Murray, Marohasy argued that there was no need for additional flows at that time and that we should test the results of current environmental measures before committing to more.House of Representatives Standing Committee on Agriculture, Fisheries and Forestry, 2004, Inquiry into future water supplies for Australia’s rural industries and communities

Public position on global warming

In a 2005 Australian Broadcasting Corporation interview she claimed that... "[i]t's not clear that climate change is being driven by carbon dioxide levels".Report released on climate change - Broadcast 7/26/05

On the Australian Broadcasting Corporation Radio National program, Ockham's Razor, Marohasy said in 2005... "I agree with Professor Flannery that we need to reduce atmospheric carbon dioxide levels", later adding "But I completely reject the concept of 'sustainability science' and I am tired of being told the sky is about to fall in".Ockham's Razor - Broadcast 11/20/05

In a 2008 interview on the Australian Broadcasting Corporation Radio National program, Counterpoint, she claimed recent cooling by starting with the extreme temperature peak of the 1998 El Niño1997-1998 El Nino: the most recent event, Department of Atmospheric Science, University of Illinois event.Interview on Counterpoint - Broadcast 3/17/2008

In 2020, during and in the aftermath of the Black Summer Bushfires, Marohasy argued that climate change was not a contributing factor, and that the extent of the natural disaster was not as severe as some claimed.

Disagreement with the Bureau of Meteorology Marohasy disagreed with the Bureau of Meteorology (BOM), claiming in the Australian mediaCourier Mail - You Call that a Category 5? that Cyclone Marcia's warning should be for a category 3 cyclone. BOM's Cyclone Marcia warning was for a category 5 cyclone.Tropical Cyclone Marcia to reach Category 5 system at landfall Marohasy cited data from Middle Percy Island stationLatest Weather Observations for Middle Percy Island showing maximum wind gusts of 208 kilometres per hour.Marohasy, "Just before the cyclone made landfall it passed over Middle Percy Island ... A wind gust of 208 km/hr was recorded at 4.30 am, which suggests Marcia was almost a Category 3 at this time" BOM stated however, that the strongest winds of the cyclone were on the eastern side, some 40 kilometres per hour faster - typical for cyclones in the southern hemisphere. The cyclone was gaining in strength. Middle Percy Island was on the western side of the cyclone. Middle Percy Island measuring equipment was destroyed by the cyclone and therefore the BOM data stream ceased. Marohasy's claim, that BOM's category 5 warning was based solely on computer modeling, was rejected by Bureau chief Rob Webb.

Jonathan Nott,Professor Jon Nott Profile - James Cook University a James Cook University specialist in extreme natural events, said the bureau numbers showed it was a category 5 rather than a 3. “I would agree with the bureau,’’ Nott said. “Percy didn’t get the strongest winds. They were substantially stronger to the east.’’
