Lydia and Wehan had a plan: travel Australia in a campervan for a few years, save up some money and buy a house.

The Western Australian couple just didn't anticipate just how difficult it would be to tick off all three items on their agenda.

Heading home after four years on the road, they discovered that re-entering the property market was not on the cards.

The solution? Stay on the road, and deck out an old patient transport van for $50,000 instead of a house.

"We previously had a four-bedroom, two-bathroom house in Perth, lived in that for probably a few years and then decided to take the leap, sell the house and fit out a van," UK-born Lydia told Nine.com.au.

"We also both had long commutes. It would be an hour train ride for me, leaving in the dark and coming back in the dark.

"And it just didn't feel rewarding or fulfilling, and when we sat down and talked about it, we both said: We want to travel, we want to see more, we want to get out there."

During their multiple laps around Australia in a different campervan, Lydia, 29, and Wehan, 28, ticked off every state and territory while living an impressively frugal lifestyle.

The pair spent around $64 per day, averaging under $2000 per month, during their last 595-day journey.

Most of the bigger expenses – particularly in recent weeks – are related to fuel and van insurance.

At first, they had planned to save enough cash to buy property again.

But that dream was quickly extinguished.

The median house price in the WA capital now sits at about $1.3 million, double what they paid in their early 20s.
