The most viable option, according to Dr Tucker, is to mine an asteroid "locally" by nudging a near-earth asteroid into the gravitational grip of the Earth, moon and sun, which will keep it hovering above the Earth.

Essentially, mining asteroids.

The Australian Asteroid Mining Project formed in August and has ambitions of getting a prototype mission off the ground by mid 2020s.

As a nation experienced in mining and on the verge of getting its own space agency, Dr Tucker said this could be Australia's opportunity to make its mark on space.

"If asteroid mining becomes successful, it will be the only time in human history when we have an infinite supply of resources," he said.

"This has the potential to change the global scheme and how mining is done and it is not that far away."
