The police discovered the house even further down the road in a storage facility near Hervey Bay, more than 1,400 kilometers, or 900 miles, from where it was stolen.
The house is mounted on a trailer and valued at about $20,000.
Julie Bray built the prototype home, worth around £12,000, for exhibition to investors, but it disappeared from her business premises on Sunday.
Though the 24-year-old man has been charged by the police in Queensland with bringing stolen property into the state, Senior Constable Troy Roberts of the Australian Capital Territory police said an investigation was continuing.
On Wednesday, Bray received word that the home had been spotted in Hervey Bay, a full 1,416km from its original starting point.
The Tiny Home is a prototype model that, when finished, will carry a price tag of somewhere in the vicinity of $30,000.
"I'm certainly very happy it has been found, as on Monday afternoon I was in despair because I thought I'd never get it back", she said.
The initial post Bray made on Facebook was shared some 400 times.
"I didn't believe it at first, but he was able to describe bits of the house that aren't in the photo", Ms Bray said. Whenever I post something about a major crisis in the world I get no response, and then something that is a bit of a crisis for me that is not almost as bad, goes insane.
The unidentified man is now scheduled to face Hervey Bay Magistrates Court on October 5th.
