RateSetter Australia, which has now matched over $11 million in personal loans, released the details of its loan book at a lender event last week.
Addressing lenders, RateSetter chief executive Daniel Foggo said transparency is "absolutely vital" to the peer-to-peer lending industry.
"In the UK and the US you can download the full loan book and return information from the main providers. In the UK, RateSetter was the first to release its loan book," Mr Foggo said.
"It’s very important if you’re taking money from retail investors … that they can understand who you’re lending to to what your performance is like," he said.
RateSetter Australia's head of operations, Glenn Riddell, said the platform only takes on "very credit-worthy borrowers", with the typical RateSetter borrower a "portrait of mid-career Australia".
"They’re in their late 30s or early 40s, and they have one child on average," Mr Riddell said.
"They have a mortgage, they’re typically married or in a de facto relationship. They’re professional, they’re in full-time work, the majority of them will own a home as well.
"Most of them are borrowing for pretty good reasons – not that we like to moralise too much about why people borrow!" Mr Riddell said.
The loan book shows that RateSetter Australia, as at 15 September 2015, had 1,501 lenders, 595 borrowers and 603 loans outstanding.
The average borrower age was 39; 65 per cent of borrowers were male; and 53 per cent of borrowers own their own home.
Gross average income per annum for a borrower was $92,683, and the average amount borrowed was $16,700 per borrower.
The top five borrowing reasons were, in order: auto finance, debt consolidation, home improvement, a holiday, and medical reasons.
Meanwhile, the average lender age was 36, with 23 per cent of funds held by self-managed superannuation funds.
RateSetter Australia's provision fund, which is funded by borrowers, sat at $560,372 as at 15 September 2015, representing 2.4 times the expected default rate.
To date, there have been zero defaults by RateSetter borrowers, with 100 per cent of lender capital and interest returned.
