A West Australian One Nation MP has decided to boycott the Diggers and Dealers Mining Forum in Kalgoorlie because there will not be a welcome to country ceremony.

Mining and Pastoral Region MP Robin Scott said he was outraged when he found out about the decision.

"For some reason this year they've decided to not have a welcome to country ceremony which is a snub to the local Indigenous people," he said.

"They're quite adamant that they've got a really tight schedule, there's no way they can allow any time for a welcome to country ceremony.

"So I told them that unless that takes place I want to get a refund on my ticket, $1,780. I said I would donate that to a Kalgoorlie charity or some worthwhile project.

"Within a few hours they had refunded my ticket.

"I was so disgusted, I just find it so disrespectful to the local Aboriginals that I had to take a stance on this."

Mr Scott said he offered to pay for the ceremony, but was told that was not the issue.

Diggers and Dealers organisers defend decision

John Langford is the organiser of next month's Diggers and Dealers event and has rejected the suggestion the move should be seen as a snub.

He said a local man different to the one who presented last year had been lined up to do the ceremony.

But then it was discovered the new presentation could run for half an hour, and was going to be more detailed and involved than expected.

Mr Langford said the welcome to country would return next year.

"We are certainly not being disrespectful to the Indigenous people," he said.

"We just took the view earlier this year that we would quietly not do it this year and reintroduce it in 2018, where we thought we could get some control over the format of the welcome to country.

"We just don't have that time in our schedule and nor do we think that ... an investment conference such as Diggers and Dealers, it's appropriate for anything other than the normal welcome to country that you see.

"Which is ... a short, sharp dignified and respectful welcome to the people at the particular event."

Mr Langford said the event, which was "jam packed" and will attract more than 2,000 people, should be no more than an investment conference.

Mr Scott said he believed the majority of Aboriginal people in Kalgoorlie were pro-mining, because it created jobs.
