He also raised home ownership and mining commitments as part of his bid to grow his party's parliamentary representation in the upcoming election.

Mr Palmer described regional communities as "the backbone of the nation" that deserved better focus from government.

"The United Australia party is committed to economic growth in rural areas. Our cities are bursting at the seams. We face heavy congestion, serious housing affordability issues, and mounting costs of living," he said.

Mr Palmer called for decentralising Australia and to encourage people to move and settle in regional areas through pledging a 20 per cent tax concession incentive to people living more than 200 kilometers from the city.

"We can decentralise Australia, encourage people to move and settle in our regional areas, thereby providing Australians with a lower cost of living and housing affordability," he said.

The housing crisis was another pledge from Mr Palmer for the United Australia Party, saying it's an "emergency that we face in this country like any other in times of war, hardship and the depression" and has pledged a home lending rate.

He said the future of increased home loan rates would see Australians lose their homes, warning "you can imagine the social disruption in our country when that happens".

Promises were made by Mr Palmer, saying the United Australia Party would use the power of the constitution to put a cap on bank home loan lending rates at a maximum of 3 per cent for the next five years.

"It's the level of debt that the Morrison Labor governments have racked up and how that level of debt will affect interest rates and current home ownership in Australia," he said.

Mr Palmer asserted the Liberal, Labor and Greens parties have "sold out our country" in allowing the country to be controlled by foreign interests, but later gave more favour to the Greens.

"I think I'd put the Greens ahead of Liberal [and] Labor. That's my personal perspective, because they haven't been in government, and they haven't been responsible for this debt," he said.

Commitments were made to iron ore, as Mr Palmer said the United Australia party would produce a 15 per cent export license for all iron ore exports from Australia and pledged the proceeds from that license would be "used for the retirement of the $1 trillion mountain of debt Australia faces".

"Australia is the dominant and only supplier of iron ore growth to Asian economies and is at the bottom of the food chain," he said.

"When our politicians lacked the courage needed to protect and defend our country to get the best bargain for our citizens, we know we need to act."
