Hidden on a property in regional WA, Terry Germain's private World War II bunker is perfectly suited to his needs.
The underground bunker, used for communications during the war, is home to the 31 rare and restored vintage motorcycles he now owns.
When a real estate agent first showed Mr Germain the 20 hectares of bushland in the state's south-west region that would one day become his, he was thrown by the presence of the bunker.
"When he first told me I thought, how will I get rid of that?" he said.
"And then I suddenly thought, hang on, I need that.
"Because I'd already got three motorbikes that I was starting to restore and I thought 'This is ideal, perfect'."
The original plans for the communications bunker hang in the entrance way and reveal it was built in 1941 and 1942.
"There were, I understand, 19 or more along the WA coast, starting down in Augusta," Mr Germain said.
"Now most of them have already been blown up and disposed off.
"It's about 70 feet long in my old language [21 metres], and it was half-buried in the ground."
A lifelong love of engines
Mr Germain stored vintage cars in the bunker at first, but once his collection of motorcycles grew they soon took over the safe underground rooms.
"I've got 31 bikes, which are mostly all restored," he said.
"About five of those just need finishing off, everyone of them I have worked on, but I haven't done a ground-up restoration on every one."
The collection includes a 1916 Triumph, a handful of Indians, Velocette models, two Nortons, three Ducatis, and BSA models.
While the location of the bunker is kept relatively secret, a few of Mr Germain's friends and fellow bike enthusiasts have been lucky enough to get a glimpse inside the hidden space.
The workshop next door to the bunker is also an impressive sight. It has hundreds of boxes containing thousands of spare parts for different models.
"I supply spare parts to my friends and anybody interested in those particular models," he said.
"I get them from everybody else's shed … every bit I earn from selling parts gets spent back on my bikes."
At 87 years of age, Mr Germain still goes for the odd ride although these days he sticks to three wheels.
"I still ride a trike, but I don't ride the solos," he said.
"I can ride them, but I threw my licence in about five years ago because I did not want to be tempted to ride in traffic anymore."
