I wrote a script to yank rates and lending product details from a few sources, de-duped them and tracked it over time. The tabs are ordered by date.
There's more than 6000 home loan lending products, this is all you'll ever need for making a decision without a broker. However keep in mind terms and conditions may differ from spreadsheet, so be sure to dot your i's and cross your t's. This is not financial advice. See @geek001's reply re: Tic:Toc. In some cases "Members Only" or package deals aren't included, this is because the data source does not list them. See Me Bank example below.
Update: I've started just uploading a daily CSV as the XSLX was getting too big. Historical CSV's available upon request.

There's a new worksheet added to the XSLX for every new day, the first sheet is just a formatted page of stale data. There's a copy of the daily data going back a few months, scroll all the way to the end for the last one.

I assume over time this information will become less available as different sources make scraping harder.
Thanks! Can you post the script?
