A PERTH march in support of white farmers in South Africa is expected to be attended by up to 3000 people, with speakers including conservative Liberal MP Andrew Hastie.

Organised by South African Events, it starts at midday on Sunday and is expected to last about two hours.

"It's going to be a big one," the organiser told AAP.

"We support land reform but not the way we're doing it now."

He said more than 2000 people recently attended a similar event in Brisbane.

WA's sole Liberal Democrats MP Aaron Stonehouse says he's going to be there.

Home Affairs Minister Peter Dutton this week said he was considering "several" applications from South African farmers for refugee or humanitarian status in Australia.
