One of the Morrison government’s strongest backers of the controversial Adani coal project, Michelle Landry, says the company has attended fundraisers for her re-election campaign, but she doesn’t have a figure on how much has been donated.

Landry, who is the LNP member for Capricornia, told the ABC on Wednesday she was not in control of her campaign finances so she wasn’t in a position to nominate a specific figure for Adani donations. She said taking financial support from a company trying to secure federal and state backing for the project “certainly doesn’t sway me”.

“My main job is to look after the people of Capricornia, and [the Adani project] is about jobs for the people of Capricornia,” the Queensland MP said. “I have the biggest coal mining electorate in this nation, and I stand up for my people here and will continue to do that”.

An analysis by the Australian Conservation Foundation of federal and Queensland donations data shows Adani has given the Liberal and National parties $60,800 since the last federal election.

One Nation has received $30,000 from Adani. Labor received $2,200, but later returned the money to the company.

The ACF’s Stop Adani campaigner, Christian Slattery, notes that Queensland has real-time donation disclosure laws, but it can take up to 18 months at the federal level for donations to be made public.

“We don’t know how much more money Adani has donated to federal political parties for this election campaign. This highlights the need for reform of Australia’s political donations regime to ensure real-time disclosure.”

The controversial Queensland coal project continues to be a significant fault line in the 2019 election campaign. The former Greens leader Bob Brown is leading a convoy protesting against the project which will travel from Hobart to central Queensland, drawing national focus to the mine.

Labor strategists report the Coalition has been successful in the opening week of the campaign in using the future of the coal industry as a campaign rallying point, and they say local media in central Queensland is amplifying the government’s message.

Queensland Nationals used the final weeks in government to pressure Scott Morrison to deliver tangible policy wins they could sell in central Queensland, like a feasibility study to examine whether a new coal plant was needed, and lobbying the environment minister Melissa Price to tick an environmental approval for the Adani project.

Labor has been mobilising significantly in Queensland, which is a do-or-die state for the Coalition in this election contest. Labor is directing considerable ground resources in Capricornia, Dawson, Flynn and also Herbert, a north Queensland seat Labor currently holds with a very slim margin.

The performance of One Nation, Clive Palmer’s party and Katter’s Australian Party in the north will influence the final result in the state, and government MPs have been bracing for a considerable protest vote.

This week’s Newspoll indicates support for Pauline Hanson’s One Nation has crashed in the wake of the al Jazeera controversy, which fortified Labor’s lead in the latest survey but also gave the Coalition its equal-best primary vote since just after the last election.

But strategists in Queensland report the protest vote remains strong in the state, and predict the slump for One Nation is more likely to be a lull than a collapse. Hanson has been visible in the campaign this week, making a public overture to the Nationals about preferences.

Coal has proved a vexed issue for the major parties in this contest. Metropolitan Liberals, under pressure from voters concerned about the government’s record on climate change, want new coal projects on the back burner, but regional MPs in Queensland have the opposite view.

Labor has also attempted to walk a line on Adani where it says it will support the project if it stacks up economically and environmentally, but it is also building a case to review the most recent groundwater approval for the project on the basis the environment minister was “bullied” by colleagues into producing a quick decision.
