The 39-year-old, who goes by the name Mick Fett, was born the year the first film in the series came out.
Since the 1990s, Fett has amassed a vast collection of action figures, costumes and other merchandise.
His collection fills the five-bedroom home he shares with his girlfriend and is estimated to be worth A$500,000 (Â£300,000; $370,000).
"I mentioned that I had some Star Wars stuff when we first got together," he told the BBC. "She was a bit overwhelmed at first and then she sort of adapted."
The suburban house is filled with a life-size Han Solo carbonite statue, priceless vintage toys and a vast collection of creatures from across the galaxy.
There's an entire room dedicated to arcade games and even a pod-racer in the backyard. Only one room does not have Star Wars memorabilia in it - the main bathroom.

"When I'm not dressing up in Star Wars costumes, I wear a uniform," he said.
"It's two different worlds. The guys at work can't believe what I do in my Star Wars time and all my Star Wars friends can't believe I'm a police officer."
The idea to redecorate the Darth Vader costume began when he attended an overseas Star Wars convention.
He originally intended to attend the event as a Stormtrooper with an Australian flag cape. But at the suggestion the idea evolved.
"One of my mates said: 'Why don't you go out and spray paint the entire costume?' I thought - instead of doing a Stormtrooper why not Vader?"
The Down Under alter ego of the Sith Lord has since become a huge hit - at home and abroad.
"I don't know whether Aussie Vader is a villain or a Rebel," he laughed. "I'm a bit of a Rogue One myself."
"One of my favourite sayings is 'May the Force be with you, mate,'" he said.
"The cape is an Australian flag. I've got beer cans on my belt and blue flames airbrushed onto my helmet and chest piece. I've even made a custom light-sabre with a didgeridoo handle."
He has already seen the new Star Wars film Rogue One, once at the red carpet premiere and again at a midnight screening with fans.
"It definitely beat all my expectations," he said, adding that the latest blockbuster is a great tribute to the original trilogy.
"Empire Strikes Back was dark and gritty. Rogue One has a lot of those elements too."

The four-storey building in Los Cristianos, on the south of the island, collapsed at 09:30 local time (08:30 GMT), emergency officials said.
The body of a woman aged about 70 was found in the rubble, local media said.
Residents living near the building said they had heard a large explosion shortly before it collapsed.
Three people were also injured in the incident, one seriously.
Nearby apartments were later evacuated over fears of a gas leak.
Arona municipality said searches for nine of the 28 people who lived in the building were continuing.
It is not clear if those who are unaccounted for were in the building when it fell. Mayor Jose Julian Mena told Spain's Efe news agency it was unclear whether anyone was trapped.
Emergency officials on the Canary Islands said (in Spanish) that a 57-year-old woman had suffered serious injuries to her upper body.
Two others, a 28-year-old Italian man and a 55-year-old woman, were also treated, the latter after a panic attack.
One nearby resident told Spain's Efe news agency there had been a strong smell of gas in the area soon after the explosion.
The owner of the Hide Away Pub, a bar next to the affected building, said his terrace had been "obliterated" by the collapse.
Javier Velazquez told British newspaper The Sun that if the blast had happened in the evening, the number of casualties would have been "far worse".
English-language newspapers on the island say the area is popular with British tourists.
