Remind me: Pick interest rate at which you'll loan money via web site(s)

So, a while ago, we discussed trade-offs of lending money - via a loan/broking web site (in AU, but similar to a UK business model).

What companies & web sites were mentioned, it as go-betweenness (between individual lenders & borrowers)?

Interest rates were higher than savings accounts pay, but there were risks. Eg, borrower wouldn't pay their loan.

Anyone recall the who, what, where (in AU)?

Thanks
